Claim 10:
11. A detection method for an operating body using 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 pressure sensor comprising a pressure sensing film that has a piezoelectric membrane having a pressure-sensitive surface and two conductive membranes provided so as to sandwich the piezoelectric membrane, one or more of the two conductive membranes is patterned, and the pressure sensor is configured to individually detect pressure at a plurality of positions in the pressure-sensitive surface,
wherein a detection surface that detects an operating body has a region in which the capacitance sensing surface and the pressure-sensitive surface overlap when viewed from a normal direction of the detection surface,
the detection method comprising:
sensing an object with the capacitance-type sensor;
sensing pressing by the object with the pressure sensor; and
if the object is sensed with the capacitance-type sensor and is sensed pressing by the pressure sensor, determining that the object is the operating body,
wherein the operating body detection device has one or more features selected from the group consisting of:
in-plane resolution of a capacitance change measurement on the capacitance sensing surface of the capacitance-type sensor being higher than in-plane resolution of pressure measurement on the pressure-sensitive surface of the pressure sensor, and
the pressure sensor being configured to divisionally measure pressure on the pressure-sensitive surface, and if an object is detected with the capacitance-type sensor, the pressure sensor measuring the pressure using a portion of the pressure-sensitive surface at which coordinates on the pressure-sensitive surface that corresponds to coordinates of the object detected with the capacitance-type sensor on the capacitance sensing surface are positioned.
