Abstract: An electric power supply cut-off circuit comprises an IC which outputs a normal operation signal when the IC is operated normally, a switch which makes connection or disconnection between the IC and a power source, and a switching control circuit which continuously outputs a connection instruction signal during a period in which the normal operation signal is inputted from the IC, wherein the switch connects the IC and the power source when the connection instruction signal is inputted, and the switch cuts off the connection between the IC and the power source when the connection instruction signal is not inputted. Accordingly, it is possible to reliably avoid any excessive increase in the temperature of the IC and the ignition of the IC.
