Abstract

Abstract The present invention relates to a biosensor comprising a working electrode base plate 11, a counter electrode base plate 14 and a reagent layer containing at least an enzyme and an electron mediator, wherein a working electrode 12 disposed on the working electrode base plate and a counter electrode 15 disposed on the counter electrode base plate are positioned so as to mutually face and a terminal of a measuring device can be brought in contact with terminals 13, 16 of both electrodes from through-holes 25, 24. Such a biosensor can produce highly reliable and accurate measuring results with only a small amount of a sample.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 61 words
A biosensor comprising a working electrode base plate, a counter electrode base plate and a reagent layer containing at least an enzyme and an electron mediator, wherein a working electrode disposed on said working electrode base plate and a counter electrode disposed on said counter electrode base plate are positioned so as to mutually face with a space between the electrodes.
Claim 2
Dependent Claim 72 words
A biosensor comprising a working electrode base plate, a counter electrode base plate, a spacer member placed between said both base plates and a reagent layer containing at least an enzyme and an electron mediator, wherein a working electrode disposed on said working electrode base plate and a counter electrode disposed on said counter electrode base plate are positioned so as to mutually face with a spacer member placed between the electrodes.
Claim 3
Dependent Claim 39 words
The biosensor in accordance with claim 1 or 2, wherein at least one of said working electrode base plate and said counter electrode base plate has a through-hole which exposes an electrode terminal of the other plate to outside.
Claim 4
Dependent Claim 81 words
The biosensor in accordance with claim 1 or 2, wherein one of said working electrode base plate and said counter electrode base plate has a cut-away portion which exposes an electrode terminal of the other base plate to outside and a lead connected to the electrode on a surface of the base plate having a cut-away portion extends, via a side surface of the base plate having a cut-away portion, to the back of the surface where the lead is connected.
Claim 5
Dependent Claim 80 words
The biosensor in accordance with claim 1 or 2, wherein one of said working electrode base plate and said counter electrode base plate has a through-hole filled with a conductive material and a cut-away portion which exposes an electrode terminal of the other plate to outside and a lead connected to the electrode on a surface of the base plate having a cut-away portion extends, via said conductive material, to the back of the surface where the lead is connected.
Claim 6
Dependent Claim 66 words
A biosensor comprising an insulating plate provided with a groove on its surface, a cover member joined to said insulating base plate to form a space for accommodating a sample in said groove, a working electrode and a counter electrode disposed so as to mutually face in said groove and a reagent layer containing at least an enzyme and an electron mediator disposed in said groove.
