A wet-type solar battery including a support composed of a light transmissive material and a stack in which a conductive layer, a photoelectric conversion layer containing a porous semiconductor, a porous insulating layer, and a counter electrode conductive layer are stacked in this order is provided. The conductive layer is divided into a first region including a portion where the photoelectric conversion layer is to be formed on a surface thereof and a second region where the photoelectric conversion layer is not to be formed. A protection film for preventing internal short-circuiting, which is not greater in film thickness than the photoelectric conversion layer, is formed in at least a part around the photoelectric conversion layer on the surface of the first region.
