CAPACITIVE INPUT DEVICE

摘要

Disclosed is a capacitive input device in which the overlap dimensions of intersection points where lower electrode patterns and upper electrode patterns intersect are regulated on the basis of the distance between an operation surface and a sensor unit, and which can easily and appropriately improve the uniformity of sensor sensitivity. The capacitive input device comprises: a sensor unit in which lower electrode patterns and upper electrode patterns are arranged so as to intersect with each other in planar view, and in which capacitance is generated at the intersection points between the lower electrode patterns and the upper electrode patterns; and a surface member which is arranged so as to face the sensor unit in the height direction, and which is provided with an operation surface on the surface thereof. The operation surface is formed having a curved surface so that when an operating body makes contact with the operation surface, the distance between the operating body and the sensor unit differs depending on the contact position of the operating body on the surface of the operation panel. The overlap dimensions of the lower electrode patterns (14a-14d) and the upper electrode patterns (13a-13d) at the intersection points (16a-16p) are formed so as to be smaller as the distance between the operation panel and the sensor unit is larger.
