Abstract: Provided is a force sensor capable of expanding the application range of an electrically conductive member having an isotropic gauge factor. The electrically conductive member is placed in a designated latitude region on a main face of the strain body to annularly extend around a pole and to be divided at a position. The designated latitude region is a latitude region in which the magnitude of the sum of a first strain amount in the longitude line direction of the strain body relative to the pole and a second strain amount in the latitude line direction is not less than a reference value when a force having a component in the perpendicular direction to the main face is applied to the strain body.
