A shift device (100) mounted on a vehicle includes a motor (11) configured to drive, by electric power supplied from a power supply (104, 105) mounted on the vehicle, a shift switching member configured to switch shift positions, a cut-off unit (34, 44) configured to cut off conduction of a power supply line (32, 42) through which the electric power is supplied to the motor, and a drive circuit unit (35, 45) configured to output the electric power to the motor and including a driving switching element configured to execute a switching operation. The shift device is configured to determine an abnormality of the power supply line when a voltage of the power supply line is smaller than a predetermined threshold value, turn off the driving switching element, and cut off the conduction of the power supply line by the cut-off unit.
