To provide a lock device of an electric power supply plug, capable of ensuring operation reliability by ensuring the reliability of a radio signal.
A lock device of an electric power supply plug 10 is mounted on a vehicle 1 performing radio communication with an electronic key 80, restricts unauthorized removal of an electric power supply plug 10 connected to an inlet 31 of the vehicle 1 through an authentication function via radio communication, and is provided with a charging ECU 75 executing permission of removal. Regarding the lock device, the vehicle 1 is provided with a plurality of antennas for transmitting radio signals, an antenna ML among them relates to permission of removal of the electric power supply plug 10, and the others relate to execution or permission of unlocking of a door. The charging ECU 75 transmits a radio signal relating to the other antennas while normally maintaining the stopping state of transmission of the radio signal relating to the antenna ML, stops transmission of a radio signal relating to unlocking of the door when transmitting a radio signal relating to removal of the electric power supply plug 10.
