Abstract
In a capacitive input switch that is accommodated in a housing of electronic equipment, the capacitive input switch includes a rigidity imparting layer having rigidity and a laminate sheet laminated on the rigidity imparting layer. The rigidity imparting layer and the laminate sheet are three dimensionally formed. The laminate sheet is formed by a substrate sheet, a conductive pattern layer for capacitor formation, and a decorative layer that is laminated at least on any one of the substrate sheet and the conductive pattern layer. A separate conductor is caused to contact with the conductive pattern layer and the conductive pattern layer is caused to be electrically connected to an external electric circuit by the conductor.
