An electronic circuit apparatus has a casing, a circuit board at which electronic members and power transistors are mounted, and a connector for connecting the circuit board with an external electrical circuit. The casing is insertion-molded by a resin, with the circuit board where the electronic members, the power transistors and the connector have been mounted being held at a predetermined position in a die for molding the casing through the resin. Thus, in the electronic circuit apparatus, damage to circuit components and noise due to a vibration excitation can be restricted, without increasing the number of construction members of the electronic circuit apparatus.
