In an input device capable of reliably detecting, when an operator brings an operating body close to or into contact with an operation plane, absolute position information irrespective of a contact area size, third electrode arrays are disposed closer to the operation plane relative to second electrode arrays in a normal direction of the operation plane, the second electrode arrays have a portion protruding from the corresponding third electrode arrays when viewed in the normal direction, and assuming that a change amount of electrostatic capacitance between first and third electrode arrays occurred by an operation of the operating body is denoted by &#x394;C1 and a change amount of electrostatic capacitance between the first and second electrode arrays occurred by an operation of the operating body is denoted by &#x394;C2, a position of the operating body in the normal direction is calculated based on a ratio &#x394;C1/&#x394;C2.

Input device

An input device includes a translucent base material having flexibility, translucent first electrode parts arranged in a sensing region on the base material in a first direction, translucent second electrode parts arranged in the sensing region on the base material in a second direction crossing the first direction, and lead wires that are electrically continuous to the first electrode parts and second electrode parts, the lead wires extending from the sensing region on the base material to a peripheral region allocated outside the sensing region. A bent portion is provided in the peripheral region on the base material. Each lead wire has a flexible conductive member on the bent portion. A covering material is provided so as cover at least part of the flexible conductive member on the base material.

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.

Input device with one directional lead wiring

An input device includes a light-transmissive panel made of synthetic resin, an electrode layer, a decorative layer disposed on an inner surface of the panel, and an inner resin layer disposed on a surface of the decorative layer. The inner resin layer has a connection pattern on a surface thereof. The connection pattern is in electrical communication with the electrode layer. The input device further includes a flexible printed circuit board joined to the surface of the inner resin layer by thermocompression bonding.
