Provided is an in-vehicle charger preventing decrease in reliability of vehicle control. An in-vehicle charger includes a charging coil (12) mounted to a vehicle including a communication device, and a control unit (6a) connected to the charging coil (12). The control unit (6a) is configured to detect a vehicle driving state based on a detection of an engine operation state of the vehicle or a parking brake release output of the vehicle. This prevents electromagnetic wave emitted from the charging coil from affecting wireless communication performed between the remote control key and a transceiver unit of the vehicle.
