Abstract: An input device that enables wires to be bent together with a base material without deteriorating translucency and conductivity of the wires has: a base material having translucency and flexibility; first electrode parts and second electrode parts, both having translucency, that are provided in a sensing region on the base material; and lead wires that are electrically continuous to the first electrode parts and second electrode parts, the lead wires extending, on the base material, from the sensing region to a peripheral region. A bent portion is provided in the peripheral region on the base material. Each lead wire has a flexible laminated body provided on the bent portion. The flexible laminated body has a first amorphous ITO layer provided on the base material, a conductive layer provided on the first amorphous ITO layer, and a second amorphous ITO layer provided on the conductive layer.

Abstract: A capacitance detection part simultaneously receive input of electric charges stored at one electrode, from a plurality of terminals provide to the one electrode. As a result of the simultaneous input, partial electric charges stored between an object and an overlapping portion of one electrode overlapping one segment are distributed as distribution electric charges to each of the plurality of terminals in accordance with a conductance from the overlapping portion to each of the plurality of terminals. The capacitance detection part generates detection data corresponding to the distribution electric charges, for each of N terminals. The element data configuration part configures M pieces of element data corresponding to M segments, on the basis of the N pieces of detection data.

Abstract: A capacitance detection device includes at least one detection electrode, a shield electrode disposed in close vicinity of the detection electrode, an AC signal source that supplies an AC signal to the shield electrode, a detection circuit that detects capacitance between a physical object in close vicinity of the detection electrode and the detection electrode on the basis of a detection signal output from the detection electrode and the AC signal output from the AC signal source, and a phase adjustment circuit provided between the AC signal source and the shield electrode. The phase adjustment circuit advances the phase of the AC signal output from the AC signal source.
