Abstract
A force detecting device includes an insulative strain element, strain sensors, and leads. The insulative strain element is electrically insulative at least at its surface. The strain sensors are formed of a piezoresistive thin film and deposited as a piezoresistive thin film pattern on the surface of the insulative strain element integrally therewith. The leads are formed of a highly conductive thin film and deposited as a highly conductive thin film pattern on the surface of the insulative strain element integrally therewith.
