PROBLEM TO BE SOLVED: To provide a pressure sensor capable of measuring a distribution of a pressure applied to a side surface over one round and having a small insensitive region and a uniform measurement sensitivity in a circumferential direction.SOLUTION: A pressure sensor includes: a wound part; and a pressure sensor sheet doubly wound around a side surface of the wound part. The pressure sensor sheet includes: a sensor part corresponding to a portion overlapping a pressure sensitive body when unwound; and a wiring part adjacent to the sensor part in a winding direction. The sensor part includes: a plurality of first wires extending in a first direction; and a plurality of second wires extending in a second direction orthogonal to the first direction. The wiring part supports the first wires drawn from the sensor part. An angular range of the sensor part in the winding direction and an angular range of the wiring part in the winding direction each correspond to one round of the side surface of the wound part.SELECTED DRAWING: Figure 3 |
