Abstract:
1. An input apparatus, comprising: an operation surface that is operated with an operation object; a plurality of first electrodes including first electrode units each having a first width and second electrode units each having a second width, the first electrode units and the second electrode units being alternately connected in a first direction parallel to the operation surface, the second width being narrower than the first width, wherein the second electrode units each have a first electrode portion and a second electrode portion that is distanced from the first electrode portion, the first and second electrode portions being formed by a first opening formed in each of the plurality of first electrodes, and wherein the first opening includes a first opening portion and a second opening portion that are formed at an interval in the first direction; a plurality of second electrodes including third electrode units each having a third width and fourth electrode units each having a fourth width, the third electrode units and the fourth electrode units being alternately connected in a second direction parallel to the operation surface, the fourth width being narrower than the third width, the second direction crossing the first direction, the fourth electrode units being respectively opposed to the second electrode units, wherein the fourth electrode units each have a third electrode portion and a fourth electrode portion that is distanced from the third electrode portion, the third and the fourth electrode portions being formed by a second opening formed in each of the plurality of second electrodes, and wherein the first opening portion is opposed to the third electrode portion, the second opening portion is opposed to the fourth electrode portion; and a detection means for detecting, based on a change in capacitance between the second electrode units and the fourth electrode units, a position where the operation object performs one of approach and touch with respect to the operation surface.
