Abstract
An object is to provide an operating body detection device having improved reliability of a capacitance-type sensor in input detection. An operating body detection device comprising: a capacitance-type sensor having a capacitance sensing surface on which a plurality of sensing electrodes is arranged; and a heat source sensing sensor comprising a heat source sensing film having a heat source sensing membrane with a heat source sensing surface. The detection surface that detects an operating body may have a region in which the capacitance sensing surface and the heat source sensing surface overlap when viewed from a normal direction of the detection surface. Preferably, the control unit that controls the capacitance-type sensor and the heat source sensing sensor starts heat source measurement with the heat source sensing sensor on condition that an object is detected with the capacitance-type sensor.
