The detection stability of a camera regarding light-emitting sections is enhanced. An input device (100) includes a tracked region in which a plurality of light-emitting sections (H) are arranged. The tracked region includes a rear tracked section (31A) located on the rear side of operation members (13, 14, and 15) in side view and a front tracked section (31B) that is located on the front side of the rear tracked section (31A) and that extends in a direction different from that of the rear tracked section (31A) in side view.
