Abstract
A power supply control apparatus controls the supplying of power through a wire. A fuse and a semiconductor switch are disposed on a current path of a wire current that flows through the wire. The fuse and the semiconductor switch are attached to a circuit board. A plurality of terminals of the fuse are connected by solder to the circuit board. A fusing portion is connected between two terminals out of the plurality of terminals. The two terminals are disposed on the current path of the wire current. The fusing portion blows according to the temperature of the fusing portion. A microcomputer issues an instruction to switch off the semiconductor switch according to the wire temperature of the wire.
