To make it possible to accurately search for a person requiring a user himself (or herself) or a person required by the user in the place of a party or in a town by a sense of a game by transmitting user's own personality inputted by a user's personality input process as a signal encoded by a searching device.

User's personality is inputted through an input keyboard 7 by depressing a user's own personal key on an input device 2 and a person required by the user himself (or herself) is inputted by depressing a requiring personal key on the device 2. When a transmission switch 12 is turned on, the user's own personality inputted by the device 2 is converted into a pulse or frequency signal by a transmission coding conversion circuit and the signal is transmitted from antenna 13. When a receiver is turned on, the required person inputted by the device 2 is converted into a pulse or frequency signal by a reception coding conversion circuit and the signal transmitted from the antenna 13 is received.
