Disclosed is a terminal box (1) for solar cell module wherein a recessed inserting portion (2d) opening upward in order to insert a connection cable (5) is formed in sidewalls (2b, 2c) which define the hollow interior (2a) of a terminal box body (2), a barrier wall (9) is arranged on the inside contiguous to the inserting portion (2d), and the connection cable (5) is press fitted to the inside of the inserting portion (2d) such that the opening of a recess formed in the barrier wall (9) in order to insert the connection cable (5) directs downward thus preventing molten resin filling the hollow interior (2a) from leaking. Furthermore, a first connection terminal (4b) for fixing the connection cable (5) previously by caulking, and a second connection terminal (4a) for soldering the output take-out wires (6a, 6b) of a solar cell module are press fitted in the terminal box body (2) thus saving the labor of field work such as the soldering work and the caulking work of cables or the output take-out wires of a solar cell module.
