  "textContent": "A power transmitting device transmitting electric power to a power receiving device includes a power transmitter (110) transmitting electric power in a contactless manner at a resonant frequency having a predetermined relation with a resonant frequency of a part, the part being provided in the power receiving device and receiving electric power, a data receiver (112) receiving from the power receiving device a random number value generated by the power receiving device each time electric power transmission of the power transmitter (110) is started, and a controller (117) determining whether or not all random number values satisfy predetermined condition. When the condition is satisfied, the controller (117) continues electric power transmission via the power transmitter (110). When the condition is not satisfied, the controller (117) temporarily stops electric power transmission, and then resumes electric power transmission via the power transmitter (110), and receives a new random number value via the date receiver (112) from the power receiving device. The controller (117) repeats stop and subsequent resuming of transmission of the electric power, and reception of a new random number value via the data receiver (112) until the new random number value satisfies the predetermined condition.",
