It is an object of the present invention to provide a wet-type solar battery (10) capable of achieving suppressed occurrence of failure due to internal short-circuiting and improving yield and a wet-type solar battery module (20) including the wet-type solar battery (10). The wet-type solar battery (10) according to the present invention is a wet-type solar battery (10) including a support (1) composed of a light transmissive material and a stack in which a conductive layer (2), a photoelectric conversion layer (4) composed of a porous semiconductor not having a dense material, a porous insulating layer (5), and a counter electrode conductive layer (6) are stacked in this order on the support (1), the conductive layer (2) has a first region on which the photoelectric conversion layer (4) is stacked and a second region on which the photoelectric conversion layer (4) is not stacked, with a scribe line (3) lying therebetween, and the photoelectric conversion layer (4) is stacked on a part of a surface of the first region and a distance D from a peripheral portion of the first region facing the scribe line (3) to a peripheral portion of the photoelectric conversion layer (4) is not smaller than 50 µm.
