In a self-power generation type transmitter, piezoelectric elements (21) are used as a power source for transmission and generated power is efficiently utilized so that the transmission of a signal requiring a relatively high electric power can be performed. The self-power generation type transmitter includes a power generating part (2) for generating electric power by applying distortion to piezoelectric elements (21), a charging part (3) for repeatedly charging generated power, and a transmitting part (4) for transmitting a signal by the charged power. When an amount of charged power reaches a level at which the signal can be transmitted, the electric power is supplied to the transmitting part from the charging part. |
