In a casing (2), there are accommodated a power-source side bus-bar (5) connected to a power source, a plurality of load side bus-bars (7) having respective terminals connected to respective electrical loads, a plurality of power devices (8) interposed between the power-source side bus-bar (5) and the load side bus-bars (7) to control power supply for the electrical loads; and a circuit baseplate (9) having a built-in driver circuit for transmitting control signals to the power devices (8). In the form of bare tips, the power devices (8) are arranged on and connected to the load side bus-bars (7) respectively. The power devices (8) are connected to the circuit baseplate (9) through wire bondings (11). The power devices (8) are also connected to the power-source side bus-bar (5) through wire bondings (12). Each load side bus-bar (7) has a tuning-fork type terminal (6) allowing an insertion of a plate-shaped terminal (50a) of a fuse (50).
