ABSTRACT:
A load cell, of the type that converts the magnitude of an applied load into an electrical signal, has a circuit board designed to facilitate wiring. The load cell includes a load cell body, strain gauges attached to the load cell body, and the circuit board which also is attached to the load cell body. The circuit board is composed of a flexible board, a wiring pattern formed on the flexible board, and soldering portions provided on the wiring pattern on either side of a bending portion at which the flexible board is bent for attachment to the load cell body. Symbol marks for identifying terminals are provided adjacent prescribed terminals of the wiring pattern formed on the circuit board.
