ABSTRACT:
A multi-axis sensor chip provided by the invention includes a semiconductor substrate having an action part having an external force action area part and non-deforming area parts, a support part supporting the action part, and connecting parts connecting the action part to the support part. The sensor chip also has strain resistance devices provided on deforming parts of the connecting parts and has temperature-compensating resistance devices provided on the non-deforming area parts. Temperature compensation is carried out exactly by means of the temperature-compensating resistance devices when an external force or a load acts on the action part, and highly accurate stress detection can be carried out.
