ABSTRACT:
A circuit structural body includes a printed circuit board having a conductive pattern constituting a power circuit including a semiconductor switching element and disposed on one surface of the printed circuit board, and a conductive pattern constituting a control circuit for controlling the semiconductor switching element and disposed on the other surface of the printed circuit board. The printed circuit board has a through-hole for mounting the semiconductor switching element to both of the conductive patterns. The circuit structural body can be manufactured by a method including the step of laminating a reinforcing plate to one surface of the printed circuit board and the step of mounting the semiconductor switching element from the opposite side to the reinforcing plate.
