A portable device searching device includes a transmitter that transmits search information to a search area near a vehicle to search for a portable device, a receiver that receives authentication information returned from the portable device as a response to the search information, and a controller that controls the transmitter and the receiver. The receiver includes an authentication portion to authenticate the portable device based on the authentication information and notifies the controller of an authentication result. The controller performs control to transmit the search information in a normal operation state, subsequently transitions to a low-power consumption state, and returns from the low-power consumption state to the normal operation state when notified of the authentication result from the receiver.
