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.
