To provide an input device for outputting control signals different from a coordinate instruction by a touching operation by a single finger to a touch pad.

An input device 1 includes: a plurality of detection areas A-E for detecting a contact to a detection surface and outputting operation signals; and non-detection areas X_A-X_D provided among the plurality of detection areas A-E and provided at an angle different from the detection surfaces of the adjacent detection areas A-E of the plurality of detection areas A-E, for not detecting the contact.
