To provide a rush current suppression circuit capable of perfectly suppressing rush current even when power supply is restarted within a short time after the power supply is disconnected.
The rush current control circuit comprises two sets of series circuits consisting of thermistors 215 and 217 and switches 212 and 213 respectively inserted in a power supply side input circuit in a power unit 2, two sets of temperature detectors 214 and 216 detecting temperatures of respective thermistors, and a selector 211 outputting a switch-on signal 102 or 103 to a switch to which a thermistor having lower detected temperature is connected by comparing detected temperatures of the two sets of the temperature sensors when power-on signal 101 for commanding power-on outside is inputted.
