1. A sensor, comprising:
a sensor unit that includes a first pressure sensor on a front side and a second pressure sensor on a rear side that are opposite to each other and detects, on a basis of pressure detection positions in an in-plane direction by the first pressure sensor and the second pressure sensor, a force in the in-plane direction; and
a separation layer that has a gap portion and is interposed between the first pressure sensor and the second pressure sensor, wherein
the separation layer has a plurality of pole portions that is formed by the gap portion and extends in a perpendicular direction perpendicular to the in-plane direction.
