1. An input device comprising:
- a plurality of keys;
a position input sensor disposed under the plurality of keys and adapted to detect an input status based on a change of electrostatic capacitance due to transfer of a finger or a conductive material on a top side of the plurality of keys;
a base sheet disposed under the position input sensor;
a push-down-input type movable contact made of a thin metal sheet and formed in an upwardly protruding dome-shape having a circular or elliptical contour and disposed under the base sheet corresponding to the positions of the keys; and
a substrate disposed under the movable contact and having a conductive region such as a wiring pattern corresponding to the movable contact, whereina columnar section is further provided at a position corresponding to the center of the movable contact in a manner sandwiched between the position input sensor and the base sheet, andthe position input sensor comprises a sensor sheet having a predetermined electrode pattern formed using a conductive material such as silver and copper, and the electrode pattern is formed in a manner avoiding the portion where the columnar section and the position input sensor come in contact with each other.

Abstract
An input device for constructing an inputting operation unit for various electronic apparatus and a method of manufacturing the input device are provided. The input device allows push-down inputting operation and position inputting operation using the same operating unit. The input device has a position input sensor provided under a key, and a base sheet having a movable contact joined to its bottom face depending on the location where the key is disposed, and a columnar section is disposed in a manner sandwiched between the position input sensor and the base sheet at the center of the movable contact.
