A bull's eye target device with a target surface section provided with a central section and a plurality of ring sections, and a circuit substrate provided so as to be spaced from the rear surface of the target surface section. The front surface side of the target surface section is formed in such a manner that the central section is raised to the greatest extent, with the plurality of ring sections becoming relatively lower as the periphery is approached, and a central pressing part and plurality of ring-shaped pressing parts are formed so as to project at the rear surface side at positions corresponding to the central section and the plurality of ring sections. The circuit substrate is provided with circular independent terminals at positions corresponding to the central pressing part and plurality of ring-shaped pressing parts of the target surface section.
