Abstract
(EN)
Provided are a pressure-sensitive touch sensor with which a pressing force of an operating surface can be recognized stably, and a pressure-sensitive touch sensor module provided with said pressure-sensitive touch sensor. An electrostatic capacitance type pressure-sensitive touch sensor (1) is provided with a main body sheet (2) in which a first electrode (18) is provided on a first surface (10a) of a base material sheet (10), and a resilient electrode sheet (3) provided with a second electrode (34) and a resilient layer (32), wherein: a wire is connected to the first electrode (18); a wire is not connected to the second electrode (34); the second electrode (34) is provided in such a way that, in a state in which the resilient layer (32) is disposed between the first electrode (18) and the second electrode (34), surfaces of the first electrode (18) and the second electrode (34) face one another; the resilient layer (32) undergoes compressive deformation in a thickness direction under a pressing force; and the pressing force is detected from a change in electrostatic capacitance resulting from a reduction in the distance between the first electrode (18) and the second electrode (34).
