ABSTRACT:
A stress sensor enduring against long-term use is provided. Accordingly, a substrate (4), which is used as both a sensor part (1) and a supporting part (2), functions as a stress sensor, in which the sensor part (1) has means for deforming a part thereof in response to a given stress and strain gauges (5) having a function for varying electric properties in response to the deformation, and in which the deforming part has a stress dispersing means (10).
