Abstract:
1. A manufacturing method for manufacturing an electronic circuit device including a circuit board with a circuit part mounted thereon, a terminal mounted on and electrically connected with the circuit board, and a casing made of a resin material sealing the circuit part, said method comprising: holding the circuit board in a cavity of a molding die of the casing such that an other face of the circuit board, opposite a mounting face of the circuit board on which the circuit part is mounted, directly closely contacts a wall face of the molding die; filling the cavity with the resin material after the holding step, the other face of the circuit board being pressed against the wall face of the molding die by resin pressure caused by the filling of the resin material into the cavity, such that the resin material envelops and seals the circuit part, the mounting face of the circuit board, and a part of the terminal, while a remaining part of the terminal and the other face of the circuit board are free from said resin material; and hardening the resin material in the cavity whereby a remaining part of the terminal and to the other face of the circuit board are exposed and an outer peripheral surface of a portion of the casing surrounding the exposed part of the terminal is disposed in a same plane as the other face of the circuit board and forms a part of an outer peripheral surface of the electronic circuit device with the other face of the circuit board.
