Abstract

A biosensor includes a supporting layer, a reference electrode layer, a working electrode layer, a counter electrode layer, and a temperature detection device, which are formed on a front surface of the supporting layer, an enzyme film that coats a surface of the working electrode layer, and a heater member formed on a back surface of the supporting layer. A biosensor cell includes a sample chamber to which a sample solution flows in and out, and the above-described biosensor.

Claims

1. A biosensor comprising:

a supporting layer;

a reference electrode layer, a working electrode layer, a counter electrode layer, and a temperature detection device, which are formed on a front surface of the supporting layer;

an enzyme film that coats a surface of the working electrode layer; and

a heater member formed on a back surface of the supporting layer.

2. The biosensor according to claim 1, wherein the supporting layer is a film.

3. The biosensor according to claim 1, wherein the heater member is formed on a surface of a base substrate, and the supporting layer, which is formed on a surface of the heater member, is a resist insulating layer.

4. A biosensor cell comprising:

a sample chamber to which a sample solution flows in and out; and

a biosensor according to claim 1, wherein the reference electrode layer and the counter electrode layer are positioned at the sample chamber so as to be capable of making contact with the sample solution, the temperature detection device is positioned at the sample chamber so as to be capable of measuring temperature of the sample solution, and the enzyme film, which coats the working electrode layer, is positioned at the sample chamber so as to be capable of making contact with a substance to be measured in the sample solution.
