ABSTRACT:
A strain sensor includes an insulating resin, e.g. polyimide resin, film formed on a beam body having a strain generating section and a wiring layer having a resistance material, e.g. nickel-chrome, layer formed on the polyimide resin film and a gold layer selectively formed on the nickel-chrome layer. A solid powder, e.g. silicon dioxide, is mixed with the polyimide resin film.
