PROBLEM TO BE SOLVED: To realize a stable and satisfactory standard-wave receiving state even in an environment in which the reception of standard waves is easy to obstruct in a household electric appliance in which a radio wave watch is built and which receives the standard waves as well as to calibrate the time automatically in the household electric appliance in which the radio wave watch is built and to hold the precise time information. SOLUTION: As a means to transmit standard waves to a radio wave watch 1 which is built in a household electric appliance 2, the standard waves which come on an electric wire to which a power-supply cord 3, attached to the household electric appliance, 2 is connected through an indoor plug socket are electromagnetically induced to conductors 4, for standard-wave detection, which are arranged in parallel in an insulating state to an electric wire A 3a and an electric wire B 3b inside the power-supply cord 3, and a standard wave high-frequency signal is detected. |
