Biosensor and measurement apparatus.

摘要

A biosensor used in conjunction with a measurement apparatus according to the present invention comprises a support (1), a conductive layer (2) composed of an electrical conductive material such as noble metal, for example gold, palladium or the like, and carbon, slits (3a) and (3b) parallel to the side of the support (1), slits (4a) and (4b) vertical to the side of the support (1), a working electrode (5), a counter electrode (6), a detecting electrode (7), a spacer (8) which covers the working electrode (5), the counter electrode (6) and the detecting electrode (7) on the support (1), a rectangular cutout part (9) forming a specimen supply path, an inlet (9a) of the specimen supply path, a reagent layer (12) formed by applying a reagent including an enzyme or the like to the working electrode (5), the counter electrode (6) and the detecting electrode (7), which is exposed from the cutout part (9) of the spacer (8), and a cover (13) which covers the spacer (8), as shown in figure 1. The so-constructed biosensor can be formed by a simple method, and a biosensor which is excellent in a measuring accuracy as well as a biosensor in which a reagent layer is placed uniformly on the electrodes regardless of a reagent liquid composition, and which has a uniform performance can be realized.
