Abstract
A biosensor is disclosed comprising a support; a conductive layer composed of an electrical conductive material such as a noble metal, for example gold or palladium, and carbon; slits parallel to and perpendicular to the side of the support; working, counter, and detecting electrodes; a spacer which covers the working, counter, and detecting electrodes on the support; a rectangular cutout in the spacer forming a specimen supply path; an inlet to the specimen supply path; a reagent layer formed by applying a reagent containing an enzyme to the working, counter, and detecting electrodes, which are exposed through the cutout in the spacer; and a cover over the spacer. The biosensor can be formed by a simple method, and provides a uniform reagent layer on the electrodes regardless of the reagent composition.

45. A method of manufacturing a biosensor comprising:
-
a roughened surface forming step of roughening the surface of an insulating support by colliding an excited gas against the surface of the insulating support in a vacuum atmosphere, an electrical conductive layer forming step of forming an electrical conductive layer as a thin film electrode which is composed of a conductive substance on said roughened surface of said insulating support; and a reagent layer forming step of forming a reagent layer on said electrical conductive layer;
wherewettability and adherence between said thin film electrode and said reagent layer is improved by the state of roughness of the roughened surface of said insulating support being reflected by said thin film electrode. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52)
