To provide an information sending-out method, a remote information sending-out device, and a remote information read system which are supplied with electric power and send and receive information without contacting and make it possible to take external information in.

A power unit Pw constitutes a power source by using an electromagnetic wave received by using an antenna system ANT2 and information is sent and received without contacting by sending and receiving the electromagnetic wave. This noncontact type remote information sending-out device IFS1 is provided with input terminals T1 to Tn and a signal processing and sequence control circuit Dsp1 receives information from an external device connected to those input terminals T1 to Tn to process it and compose detection information and sends it as an electromagnetic wave to a remote information reader RW from the antenna system ANT2 through a transmitting and receiving circuit Tr.
