Power supply control device

A vehicle power supply control device that controls power supply via a semiconductor switch by switching the semiconductor switch ON or OFF, comprising:

• a fuse;
• and
• a circuit board on which the semiconductor switch and the fuse are mounted,
• wherein the fuse includes:
• a plurality of long plate-shaped terminals arranged in a row;
• a fusing portion connected to two terminals of the plurality of terminals;
• and
• a housing covering the fusing portion and a part of the terminals, and
• the two terminals of the plurality of terminals are arranged in a current path of a current flowing through the semiconductor switch,
• the current flows through the fusing portion,
• the fusing portion is fused when a temperature of the fusing portion exceeds a predetermined temperature, and
• the housing is heat-resistant.
