Abstract: PURPOSE: To provide a force converter which is embodied in a small construction, ensures improved signal-noise ratio, high reliability, improved performance and long lifetime, and which can be produced at a cost to assure high competitive power. CONSTITUTION: A force converter 10 includes a thin and long lever arm 12 installed on a base board having a central part and a flat tab region protruding outward from the central part along the first and the second orthogonal force sensing axis. When the external force is hitched at the free end 14 of this lever arm 12, the base board receives concentrated strain in the joint part between the tab region and central part. Thick film strain gauges 24, 26 are directly printed on the base board, at least in the first and the second position, and electroconductive pads on the board are coupled electrically with the strain gauge material in the specied positions so that the first strain gauge arranged along the first force sensing axis and the second strain gauge arranged along the second force sensing axis are partitioned.
