Abstract
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 includes a pressure sensing body composed of composite ceramics in which a material having a pressure resistance effect is dispersed on a matrix made of an electrical insulation ceramic material and a pressure receiving body having an electrical insulation characteristic and disposed on a pressure receiving surface of the pressure receiving body, wherein the pressure sensing body and the pressure receiving body are integrated with each other.
