A sensor sheet is manufactured by forming a conductive heat-sensitive materialover first wiring electrodesand forming second wiring electrodesover the conductive heat-sensitive material. For this reason, no adhesion surface (boundary surface), which is formed when adhesion is performed later, exists between the first wiring electrodeand the conductive heat-sensitive materialand between the conductive heat-sensitive materialand the second wiring electrodes

Sensor sheet

Capacitance element electrodes (Eto E) and a grounded reference electrode (E) are formed on a substrate (). A displacement electrode () that is Z-axially displaced in accordance with a Z-axial movement of a detective member () externally operated, is disposed so as to be opposed to the above electrodes (Eto E). The displacement electrode () cooperates with the reference electrode (E) and the capacitance element electrodes (Eto E) to form capacitance elements (Cto C), respectively. Each of the capacitance elements (Cto C) is connected to the capacitance element (C) in series in relation to an externally input signal. Changes in the capacitance values of the capacitance elements (Cto C) when the detective member () is moved, is detected by a signal processing circuit having hysteretic characteristics. Thereby, the displacement of the detective member () is detected.
