Abstract

PURPOSE:To obtain a high-precise measuring device which is easy to manufacture, and has a high mass productivity, by a method wherein an insulating film is formed directly on a surface of a beam body, a metal layer for strain gauge resistance is directly formed thereon, and said layer is further covered with a metal layer for temperature compensation and a metal layer for lead pattern. CONSTITUTION:A metal layer 12 for strain gauge resistance is formed directly on an insulating film 11 formed directly on a surface of a beam body 1 for bringing a load to be measured into an operation. Other part than a plural number of strain gauge resistor patterns R1-R4, consisting of the metal layer 12 for strain gauge resistance, bridge balance compensating resistor patterns R01, R03, and a span temperature characteristic non-rectilinear compensating resistance pattern Rc, which are all left uncovered, is coverd thereon with a metal layer 13 for temperature compensation. Other part than bridge balance temperature compensating resistor patterns RT1, RT3 and a span resistor pattern R5 for temperature compensation, which are left uncovered, is covered thereon with a metal layer 14 for load pattern.
