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.
