ABSTRACT:
An electric connection box include a power supply lead frame, a plurality of external connection terminals, a housing member having connector housing portions formed integrally at its outer peripheral portion and also having the lead frame and the external connection terminals insert molded therein, a plurality of transistors mounted in a bare chip condition on an upper surface of the lead frame, a circuit board mounted within the housing member, and bonding wires connecting the transistors, the external connection terminals and the circuit board to each other. Upper surfaces of bonding wire connection portions of the external connection terminals, upper surfaces of output terminal pad portions and control terminal pad portions formed on upper surfaces of the transistors, and an upper surface of a circuit pattern on the circuit board are disposed generally at the same height, thereby enhancing the efficiency of a bonding operation.
