Abstract:
1. A biosensor, comprising: a first base material having an insulating surface; a first adhesive layer located on the insulating surface of the first base material; and an electrode system and wiring sections fixed to the first base material via the adhesive layer; wherein: the electrode system includes top electrode layers and bottom electrode layers, and the bottom electrode layers are formed of a material having a higher conductivity than that of the top electrode layers; the electrode system includes a working electrode and a counter electrode, and also includes an enzyme reaction section located on the working electrode, the enzyme reaction section containing an enzyme and an electron acceptor; the bottom electrode layers and the wiring sections are integral with each other, each of the top electrode layers contains a carbon pigment and an organic binder and each of the top electrode layers has a thickness of 0.3 μm or greater and 2 μm or less, and each of the top electrode layers covers at least a part of a top surface and side surfaces of each of the bottom electrode layers, respectively.
