PROBLEM TO BE SOLVED: To set the cycle of a high-frequency radio wave intermittently transmitted from a high-frequency transmitting circuit of a transmitter to a receiver to an arbitrary cycle desired by a user, and achieve power-saving by restraining wasteful power consumed by the transmitter. SOLUTION: A transmitter carried by a poriomania person is provided with an oscillator 10 for generating a reference clock, a timing generating circuit 11 for generating a timing signal from the reference clock oscillated by the oscillator, an intermittent transmission cycle setting device 12 for setting the intermittent transmission cycle of a timing signal to intermittently transmit a high-frequency radio wave, a high-frequency transmitting circuit 14 for intermittently transmitting the high-frequency radio wave in the intermittent transmission cycle set by the intermittent transmission cycle setting device, and a power supply control switch 17 for controlling the power supply to the high-frequency transmitting circuit in the intermittent transmission cycle set by the intermittent transmission cycle setting device.
