Abstract: A control target device is specified using a remote control device with a simple configuration. The remote control device includes: a communication unit that receives a received signal strength from each of a plurality of electronic devices and transmits a predetermined control command to a control target device; and a control target device specifying unit that specifies, as the control target device, a device having a maximum variation of the received signal strength among the plurality of electronic devices. The communication unit includes an antenna disposed at an end of a housing, and the antenna has directivity at which a direction in which the end of the housing is directed to a reception side is a substantially null direction.
