PROBLEM TO BE SOLVED: To attain the size reduction of a power source wire wired in an automobile. SOLUTION: A semiconductor with fuse function (IPS (intelligent power switch)) mounted to a printed board is used as a fuse provided at the power source wire wired in the automobile, an input end of a power source circuit of the printed board provided with the semiconductor with a fuse function is connected to the power source wire at the power source side, and an output end of the power source circuit is connected to a load through a load side power source wire. The semiconductor with fuse function sets a shut-off current value while making it correspond to a load current flowing in the load, and the electric wire having an allowance current value corresponding to the shut-off current value set by the semiconductor with the fuse function is made to be the load side power source wire.
