Abstract: Provided is a technique capable of suppressing reduction of a mediator in a stored state. A reagent layer (an enzyme layer 106b, a mediator layer 106c) stacked separately on a hydrophilic layer 106a containing a hydrophilic polymer having a double bond of oxygen atoms contains an enzyme, a mediator, and a hydrophilic polymer having no double bond of oxygen atoms. Accordingly, since the mediator is surrounded by the hydrophilic polymer having no double bond of oxygen atoms, the mediator contained in mediator layer 106c can be prevented from coming into contact with CMC as the hydrophilic polymer in hydrophilic layer 106a, and reduction of the mediator by the hydrophilic polymer having a double bond of oxygen atoms in hydrophilic layer 106a can be suppressed, in the stored state.

Abstract: Provided is a technique capable of easily manufacturing a biosensor in which each of an enzyme layer and a mediator layer contains a hydrophilic polymer having no double bond of oxygen atoms and thereby which can be stored for a long period. Since an enzyme layer and a mediator layer are formed together as a reaction layer, there is no need to individually form enzyme layer and mediator layer on a cover layer and an electrode layer, respectively, as in a conventional biosensor, and reaction layer can be easily formed. Since each of enzyme layer and mediator layer contains the hydrophilic polymer having no double bond of oxygen atoms, a reaction between an enzyme and a mediator can be suppressed, and reduction of the mediator in mediator layer can be suppressed, in a stored state. Therefore, a biosensor which can be stored for a long period can be easily manufactured.
