ABSTRACT:
A stress sensor having a post (6) fixed to or integrated with the surface of an insulation substrate (1) capable of determining the direction and magnitude of a stress applied to the post (6) from changes in the characteristics of a strain gauge (2) made by a stimulus to the strain gauge (2) caused by the stress, wherein a stress to the post (6) can be converted efficiently into changes in the characteristics of the strain gauge (2). Consequently, the stress sensor has a strain gauge (2)-disposed member provided with a locally-easy-to-deform portion where the strain gauge (2) is disposed. The strain gauge (2) is a resistance element (8) and is disposed on the surface of the insulation substrate (1), the insulation substrate mainly contains a resin material, and the easy-to-deform portion is preferably a thin-wall portion (7).
