ABSTRACT:
A biosensor includes a pair of conductive lead parts formed on an insulating substrate, a working electrode and a counter electrode formed at the ends of the conductive lead parts, respectively, and a reaction layer formed so as to bridge the electrodes and react with a measurement target substance in a specimen liquid. The biosensor measures the content of the measurement target substance from an electric current value based on the reaction between the measurement target substance and the reaction layer, which current value is obtained through the pair of conductive lead parts. The reaction layer is not provided above at least one of the conductive lead parts so that the reaction layer and the conductive lead parts do not contact directly even when pin holes or cracks are generated in the electrodes.
