PROBLEM TO BE SOLVED: To obtain a motor controller in which a dark current is prevented from flowing through a controller by interrupting the power supply to the controller after resetting the motor load when a key switch is opened. SOLUTION: A power supply on/off circuit 303 is inserted between a battery 1 and the input terminal of a constant voltage power supply 304 for a controller 305. The power supply on/off circuit 303 comprises a power supply on/off control switch inserted between the battery 1 and the constant voltage power supply 304 and being turned on upon receiving a trigger signal from the battery 1 through a key switch 6, and a trigger signal supply control switch acting after the key switch 6 is opened and the load of a motor 2 is reset to interrupt trigger signal supply to the power supply on/off control switch.
