Abstract

A battery is appropriately housed in a transparent body. A transparent body includes: a transparent body main part; a defogger that removes fog on the transparent body main part; and a battery that supplies electric power to the defogger. The battery includes: a positive electrode where a transparent positive electrode conductive film and a transparent positive electrode layer are laminated on an insulating transparent positive electrode side housing; a negative electrode where a transparent negative electrode conductive film and a transparent negative electrode layer are laminated on an insulating transparent negative electrode side housing; and a transparent electrolyte layer that is arranged between the positive electrode layer and the negative electrode layer which face each other. A film thickness of each of the positive electrode conductive film, the negative electrode conductive film, the positive electrode layer, and the negative electrode layer is such a thickness as to prevent absorption of visible light of incident light to promote transmission.
