A force sensor comprises a deformation body having a closed-loop shape and a detection circuit for, on the basis of the elastic deformation of the deformation body, outputting an electrical signal indicating the force or moment that has acted. The deformation body comprises: at least two fixed parts, at least two force reception parts that are adjacent to the fixed parts along the path of the closed-loop shape of the deformation body, and deformation parts that are each positioned between a fixed part and force reception part that are adjacent along the path of the closed-loop shape. Each of the deformation parts comprises: a main bent part having a main bent surface that is bent, a fixed-part-side bent part that connects the main bent part and the fixed part corresponding thereto and hasa fixed-part-side bent surface, and a force-reception-part-side bent part that connects the main bent part and the force reception part corresponding thereto and has a force-reception-part-side bent surface. The bent surfaces
