A connecting member such as a terminal base is used, which allows a printed circuit board unit in which circuit elements such as a power module are mounted on a printed circuit board to be rated at higher current as compared to a conventional printed circuit board unit; and therefore an increase in size of the unit can be reduced or prevented with a simple configuration of connection sections. The connecting member of an electrical circuit connects the circuit element of the electrical circuit including the printed circuit board, to an electrical wire. The connecting member includes a terminal connecting section to be directly connected to terminal pins of the circuit element; a wire connecting section to be connected to the electrical wire; and attachment sections for attaching the connecting member to the printed circuit board.
