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 Wheatstone is placed 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 provided with a resistor pattern forming a bridge circuit and a span adjustment resistor pattern inserted into the input side portion of the terminal lead pattern to the bridge circuit, the span adjustment resistor pattern is divided into a plurality of parts. A load cell characterized in that the load cells are inserted and arranged in a distributed manner in the input side portion.
