Abstract:
This strain sensor makes it easy to detect strain in an object. One embodiment of this strain sensor detects strain in a strain body and comprises: a package substrate; a base substrate that is disposed on the package substrate and comprises an electrical wiring unit; a sensor substrate that is disposed on the base substrate and comprises a plurality of piezoresistance elements; and a mold resin that covers the base substrate and sensor substrate on the package substrate.
