Abstract
A sensor substrate includes a plurality of piezoresistance elements. The electrical resistance of each piezoresistance element changes in accordance with an amount of displacement of a displacement portion displaced by an external load applied through a pressure receiving unit. A base substrate supports the sensor substrate. The sensor substrate and the base substrate each include a support supporting the displacement portion such that the displacement portion can be displaced and a plurality of electrically connecting portions electrically connected to the plurality of piezoresistance elements. The supports of the sensor and base substrates are joined to each other and the plurality of electrically connecting portions of the sensor and base substrates are joined to each other. Furthermore, in each of the sensor and base substrates, either the support or the plurality of electrically connecting portions or both extend to the periphery of the sensor substrate or the base substrate.
