When a plurality of solar battery modules are to be connected, terminals formed on the rear surfaces of these solar battery modules are connected by electric wires. This wiring is very cumbersome work, so power output wires from a plurality of solar battery modules get tangled together to cause connection errors. In a solar battery module including a cover member for supporting a photovoltaic element, and a structure support member having a portion which forms an angle or a curved surface with respect to the cover member, an electric connecting terminal is formed at an opening of the structure support member, and a locking member at least partially formed by a continuous body is inserted into the structure support member. In this way, the solar battery module is fixed and/or electrically connected.
