Abstract
Abstract A thermistor includes a rectangular parallelepiped thermistor element, electrodes formed over the entire top and bottom surfaces of the thermistor element, and leads connected to the electrodes. The leads have connecting portions for deriving signals, and are bent such that the connecting portions are positioned on substantially the same plane. A sealing resin completely surrounds the thermistor element, the electrodes, and all of the leads except for the connecting portions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
A thermistor as an electronic part comprising: a rectangular parallelepiped thermistor element, said thermistor element having a top surface and a bottom surface; a first electrode formed over the entirety of said top surface of said thermistor element, and a second electrode formed over the entirety of said bottom surface of said thermistor element; a first lead connected to said first electrode, said first lead including a contacting portion in contact with said first electrode and a connecting portion for deriving signals, and a second lead connected to said second electrode, said second lead including a contacting portion in contact with said second electrode and a connecting portion for deriving signals, said first and second leads being bent such that said connecting portion of said first lead and said connecting portion of said second lead are positioned on substantially the same plane, thereby allowing said thermistor to be mounted on a substrate; and a sealing resin completely surrounding said thermistor element, said first and second electrodes, and all of said first and second leads except for said connecting portions.
Claim 2
Dependent Claim
179 words
A thermistor as an electronic part comprising: a rectangular parallelepiped thermistor element, said thermistor element having a top surface and a bottom surface; a first electrode formed over the entirety of said top surface of said thermistor element, and a second electrode formed over the entirety of said bottom surface of said thermistor element; a first lead connected to said first electrode, said first lead including a contacting portion in contact with said first electrode and a connecting portion for deriving signals, and a second lead connected to said second electrode, said second lead including a contacting portion in contact with said second electrode and a connecting portion for deriving signals, said first and second leads being bent such that said connecting portion of said first lead and said connecting portion of said second lead are positioned on substantially the same plane, thereby allowing said thermistor to be mounted on a substrate; and a sealing resin completely surrounding said thermistor element, said first and second electrodes, and all of said first and second leads except for said connecting portions.
Claim 3
Dependent Claim
24 words
A thermistor as defined in claim 1, wherein said thermistor element is supported separately apart from the substrate by said first and second leads.
Claim 4
Dependent Claim
25 words
A thermistor as defined in claim 1, wherein said connecting portions and a bottom surface of said sealing resin are substantially in the same plane.
Claim 5
Dependent Claim
27 words
A thermistor as defined in claim 3, wherein said connecting portions of said leads are substantially parallel to said top and bottom surfaces of said thermistor element.
Claim 6
Dependent Claim
22 words
A thermistor as defined in claim 4, further comprising bonding wires connected to said connecting portions of said first and second leads.
