1. A control device used in a power receiving device that contactlessly receives power from a power transmitting device, the control device comprising:
a control portion configured to:
control a power supply portion that supplies power to a load based on received power received by a power receiving portion in the power receiving device from the power transmitting device; and
in a case where the power receiving portion, after receiving a first signal having a first frequency from the power transmitting device, has received a second signal from the power transmitting device, the second signal having a second frequency that is different from the first frequency:
in a case of having judged that a time length of a reception period during which the power receiving portion has received the second signal is a first length, specify that an issued communication data issued by the power transmitting device is first communication data; and
in a case of having judged that the time length of the reception period is a second length that is different from the first length, specify that the issued communication data is second communication data that is different from the first communication data.
