1. A biosensor comprising:
- a proximal end and a distal end;
a first layer having a first length and a second layer having a second length, the first and second layers being fixed together by a third layer having a third length;
a tapered part located at the proximal end;
a working electrode provided on a first layer and a counter electrode provided on a second layer, wherein the tip part of the working electrode is provided on the tapered part; and
wherein leads for the working and the counter electrodes extend from the tapered part to the distal end.

Abstract
A biosensor comprises a space part for sucking and housing a sample formed of two upper and lower plates, the two plates being stuck together by an adhesive layer, the space part for sucking and housing the sample being constituted so as to be partially opened in the peripheral part and partially closed by the adhesive layer, and has a working electrode having at least glucose oxidase immobilized thereon and a counter electrode on the same plane of the plate.

24. A method of measuring a concentration of an analyte in a subject, the method comprising:
-
contacting body fluid of the subject with a biosensor to generate an electrical signal, the biosensor having a proximal end and a distal end, at least three layers, a working electrode provided on a first layer and a counter electrode provided on a second layer, a tapered part located at the proximal end, and a tip part of the working electrode provided on the tapered part, wherein the three different layers have different lengths and leads for the working and counter electrodes extend from the tapered part to the distal end, and determining from the generated electrical signal a concentration of an analyte in body fluid. - View Dependent Claims (25, 26, 27, 28, 29, 30)
