A load cell has strain gage resistors, lead portions for connecting them in a bridge and compensating portions for the compensation of the bridge balance, span or the like, which are laminated as metal thin films by means of the thin film technique. A protection film is formed over the metal thin films and trimmed by laser beams, and the protection film is made of a pigmented protection film made of synthetic resin for easy and accurate trimming.
