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 the metal material is placed in the strain-generating region of the beam body and connected to at least the terminal lead pattern by the terminal lead pattern. In a load cell provided with a resistor pattern forming a Wheatstone bridge circuit and a compensating resistor pattern, the compensating resistor and pattern are connected to a part of the terminal lead pattern and are opposed to each other. What is claimed is: 1. A load cell comprising: a pair of connection parts; and a plurality of resistance value adjusting parts which are connected in parallel to each other and have different surface configurations.
