Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A laminated electronic device comprising: plural base sheets which are laminated; a conductor provided on each of the base sheets; and at least two through-holes in the conductor on each of the base sheets for connecting the conductors electrically, said at least two through-holes being formed in a staggered relationship along the conductor on each of the base sheets.
Claim 2
Dependent Claim
59 words
A laminated electronic device comprising: plural base sheets which are laminated; a conductor provided on each of the base sheets; and at least two through-holes in the conductor on each of the base sheets for connecting the conductors electrically, said at least two through-holes being formed in a staggered relationship along the conductor on each of the base sheets.
Claim 3
Dependent Claim
24 words
A laminated electronic device as claimed in claim 1, wherein a coil is formed by connecting the conductors electrically in series through the through-holes.
Claim 4
Dependent Claim
71 words
A laminated electronic device comprising: plural base sheets which are laminated; a first conductor and a second conductor provided on each of a first base sheet and a second base sheet, respectively; and at least two through-holes in the first conductor of said first base sheet for electrically connecting the first conductor with the second conductor, said at least two through-holes being formed in a staggered relationship along the first conductor.
Claim 5
Dependent Claim
71 words
A laminated electronic device comprising: plural base sheets which are laminated; a first conductor and a second conductor provided on each of a first base sheet and a second base sheet, respectively; and at least two through-holes in the first conductor of said first base sheet for electrically connecting the first conductor with the second conductor, said at least two through-holes being formed in a staggered relationship along the first conductor.
Claim 6
Dependent Claim
32 words
A laminated electronic device as claimed in claim 3, wherein a coil is formed by electrically connecting the conductors located on a plurality of said base sheets in series using the through-holes.
Claim 7
Dependent Claim
63 words
A laminated electronic device as claimed in claim 3, wherein said second base sheet further includes: two connecting portions formed in said second conductor having diameters which exceed a diameter of remaining portions of the second conductor, said two connecting portions being aligned with the two through-holes of said first conductor when said first and second base sheets are laminated to one another.
Claim 8
Dependent Claim
46 words
A laminated electronic device as claimed in claim 5, further including: protective base sheets made of a magnetic material and being laminated to a side of said first base sheet opposite a side of said first base sheet to which said second base sheet is laminated.
Claim 9
Dependent Claim
59 words
A laminated electronic device as claimed in claim 6, wherein the conductors formed on said first and second base sheets are serially connected to form a coil structure, said through-holes being located at a mid-point of the coil structure formed on the first and second base sheets when said first and second base sheets are laminated to one another.
Claim 10
Dependent Claim
32 words
A laminated electronic device as claimed in claim 7, further including: a conductive paste covering said laminated electronic device so as to expose lead electrodes at opposite ends of said coil structure.
