A solar cell module comprises at least: a first light guide body having a first main surface, a second main surface, and a first end surface, which is in contact with the first main surface and the second main surface, and allowing external light to enter the first light guide body from at least the first main surface thereof, propagate through the inside, and exit from at least the first end surface; a second light guide body having a first main surface, a second main surface, and a first end surface, which is in contact with the first main surface and the second main surface, and allowing the light, which is emitted from the first end surface of the first light guide body, to enter the second light guide body from the first main surface thereof, propagate through the inside, and exit from at least the first end surface; and a solar cell element for receiving the light emitted from the first end surface of the second light guide body. The first light guide body is provided, at least on the second main surface side thereof, with: a reflection surface for reflecting light, which enters the first light guide body from the first main surface thereof, and changing the advance direction of the light; and a transmission surface for allowing the light, which enters the first light guide body from the first main surface thereof, to propagate therethrough and exit to the outside.
