Claims

[Scope of utility model registration request]

A metal material is directly laminated on the insulating coating formed directly on the beam body on which the load to be measured acts, and is arranged at least in the terminal lead pattern and the strain-generating region of the beam body and connected by the terminal lead pattern. In a load cell equipped with a resistor pattern that forms a Wheatstone bridge circuit, a terminal board is provided on the insulating film, which is formed by providing a wiring pattern on an insulating plate with poor thermal conductivity near the terminal part of the terminal lead pattern. A load cell characterized in that the terminal plate and the terminal part are connected by wire bonding, and one end of a lead wire is soldered to the terminal plate.
