Abstract
Provided is a strain sensor which includes: a linear bearing including a first member and a second member which are supported such that the first member and the second member are relatively movable only in an axial direction of a predetermined axis; a connecting member including fixed portions, which are respectively fixed to the first member and the second member, and a strain generation portion which connects the fixed portions with each other; and a strain detecting element disposed on the connecting member so as to be capable of detecting strain in at least a moving direction.
