Abstract: An electrode member includes a first electrode pattern and a second electrode pattern. In each of the first electrode pattern and the second electrode pattern, first end portion wires of the first thin metal wires form a pair across the insulation gap, and first end surfaces of the paired first end portion wires are located so as to include portions that face each other with a predetermined distance therebetween in a direction that intersects a first direction. In each of the first electrode pattern and the second electrode pattern, second end portion wires of the second thin metal wires form a pair across the insulation gap, and second end surfaces of the paired second end portion wires are located so as to include portions that face each other with a predetermined distance therebetween in a direction that intersects a second direction.

Abstract: 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 ΔC1 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 ΔC2, a position of the operating body in the normal direction is calculated based on a ratio ΔC1/ΔC2.

Abstract: A capacitive sensor has first electrodes, a second electrode, and a third electrode, which are disposed at places where a manipulating body that is part of a human body such as a finger is detected. The capacitive sensor also has a capacitance detecting means and a deciding means. The deciding means identifies the number of manipulating bodies and directions (positions) according to the capacitances of the first electrodes, second electrode, and third electrode.
