Abstract
A pressure sensor is a pressure sensor that includes: a capacitive sensor electrode layer that includes a plurality of sensing units; a first reference electrode layer that faces a first surface of the sensor electrode layer; a second reference electrode layer that faces a second surface of the sensor electrode layer; an elastic layer disposed between the first reference electrode layer and the sensor electrode layer; and a gap layer disposed between the second reference electrode layer and the sensor electrode layer. In the pressure sensor, the sensor electrode layer, the first reference electrode layer, and the second reference electrode layer have a slit.
