Claims

[Scope of utility model registration request]

a cantilever beam body having a strain-generating portion and on which a load to be measured acts; an insulating coating formed directly on two surfaces of the beam body that are orthogonal to the direction of load application and facing each other; Two strain gauge resistor patterns are formed by directly laminating and layering metal materials facing the strain-generating portion on an insulating film covering one side, and on an insulating film covering the other side. A metal bonded material is directly laminated facing the strain-generating portion, and a metal material is directly laminated on the other two strain gauge resistor patterns formed, and an insulating coating covering the two surfaces. A) one-terminal lead pattern is formed by connecting the two strain gauge resistor patterns on the same surface, and a one-terminal lead pattern is formed by connecting the two terminal lead patterns to each other, and the four strain gauge resistors are connected to each other. A load cell characterized by comprising a wiring member for connecting a pattern to a Wheatstone bridge circuit.
