Load sensor

A load sensor comprising:

• 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, wherein
• the element part includes an electrically-conductive elastic body that is electrically conductive and that forms one pole for the capacitance,
• 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,
• the fixation tool is an eyelet,
• the electrically-conductive elastic body has a hole configured to allow the eyelet to pass therethrough, and
• with the copper wire caused to extend along an outer periphery of the eyelet, the eyelet is passed through the hole and the eyelet is crimped, whereby the copper wire is connected to the electrically-conductive elastic body.

A load sensor comprising:

• an element part in which capacitance changes in accordance with a load, wherein the element part includes an electrically-conductive elastic body that is electrically conductive and that forms one pole for the capacitance;
• a circuit connection terminal configured to connect the element part to an external electronic circuit;
• a first copper wire having a first end shaped into a loop that is electrically in contact with a surface of the electrically-conductive elastic body, and a second end connected to the circuit connection terminal;
• and
• a second copper wire extending across the electrically-conductive elastic body while remaining in contact with the surface of the electrically-conductive elastic body, wherein the second copper wire being is covered by a dielectric body and forms another pole for the capacitance, and one end of the second copper wire is connected to the circuit connection terminal in order to detect change in the capacitance.
