Abstract
A load sensor includes: an element part in which capacitance changes in accordance with a load; a copper wire drawn from the element part in order to detect change in the capacitance; and a fixation tool configured to fix the copper wire to the element part. The element part includes an electrically-conductive elastic body that is electrically conductive and that forms one pole for the capacitance, and the fixation tool presses and fixes the copper wire to a surface of the electrically-conductive elastic body so as to be movable with respect to the surface of the electrically-conductive elastic body in accordance with elastic deformation of the electrically-conductive elastic body.
