Abstract
A force sensor includes: a deformable body having a force receiving portion and a fixed portion; a displacement body configured to generate a displacement by elastic deformation generated in the deformable body; and a detection circuit configured to detect an applied force on the basis of the displacement generated in the displacement body, in which the deformable body includes: a tilting portion arranged between the force receiving portion and the fixed portion; a first deformable portion that connects the force receiving portion and the tilting portion; and a second deformable portion that connects the fixed portion and the tilting portion, the displacement body includes a displacement portion connected to the tilting portion and separated from the fixed portion, the detection circuit includes a first displacement sensor and a second displacement sensor arranged in the displacement portion, and the detection circuit outputs a first electric signal indicating an applied force on the basis of a detection value of the first displacement sensor, and outputs a second electric signal indicating an applied force on the basis of a detection value of the second displacement sensor, and th…
