MECHANICAL QUANTITY SENSOR ELEMENT, LOAD SENSOR ELEMENT, ACCELERATION SENSOR ELEMENT, AND PRESSURE SENSOR ELEMENT

摘要

An object of this invention is to provide a dynamic quantity sensor device capable of measuring a dynamic quantity at a high precision and securing insulation of a pressure sensing body easily. This dynamic quantity sensor comprises a pressure sensing body 11 composed of composite ceramics in which material having pressure resistance effect is dispersed on a matrix made of electrical insulation ceramic material and a pressure receiving body 12 having electrical insulation characteristic and disposed on a pressure receiving surface of the pressure receiving body 11, wherein the pressure sensing body and the pressure receiving body are integrated with each other.
