A convenient electronic circuit in which a switch is able to be switched through electric power obtained using weak radio waves is provided. An electronic circuit includes: a switch configured to switch a connection state between a power supply configured to output DC electric power and a load; a first antenna capable of receiving radio waves; a second antenna capable of receiving radio waves; a first power conversion circuit configured to convert electric power received by the first antenna into DC electric power and output the converted DC electric power from a first DC power output terminal; a second power conversion circuit configured to convert electric power received by the second antenna into DC electric power and output the converted DC electric power from a second DC power output terminal; and a control circuit configured to switch a connection state of the switch when a difference between electric power input from a first input terminal and electric power input from a second input terminal is larger than a predetermined value.
