An object of the present invention is to provide a biosensor which exhibits good reproducibility of the amount of an immobilized physiologically active substance by suppressing plane deterioration (separation of a metal film from a resin) which occurs at the formation of a thin metal film layer on a resin surface. The present invention provides a biosensor which is produced by performing plasma irradiation on a light-reflecting surface of an optical block which is obtained by molding a resin and has at least 3 surfaces including a light incident surface, the light-reflecting surface and a light-emerging surface; forming a first metal layer; and then forming a second metal layer on the side of the first metal layer which is opposite to the light-reflecting surface.
