Input device with reinforcement plate and wider grounding wire

Abstract

An input device includes a support base, a sensor unit including electrode portions, an extended portion extending outward from the support base, a lead-out wire in conduction with the electrode portions, a grounding wire adjacent to the lead-out wire, the lead-out wire and the grounding wire being along a first major surface of the extended portion, and a reinforcement plate on a part of a second major surface opposite to the first major surface and on the side of the support base from the tip. When viewed from a normal direction of the second major surface, the grounding wire is greater than the lead-out wire, an end-portion projection line formed by a support-base-side end portion of the reinforcement plate is nonlinear, and a most-protruding location in the end-portion projection line closest to the support base overlaps the grounding wire.
