A pressure-sensitive sensor includes a first electrode, a second electrode, and a conductive resin located between the first electrode and the second electrode, wherein the conductive resin includes a first region, and a second region different from the first region in thickness in a direction in which the first electrode and the second electrode are arranged, and the second region surrounds the first region. Further, the thickness of the second region is thicker than the thickness of the first region. Further, a center of the first electrode is located within the first region in a plan view from the direction in which the first electrode and the second electrode are arranged.
