Electronic Device, Pressure Sensor, Altimeter, Electronic Apparatus, and Moving Object

The invention provides an electronic device with excellent reliability. Furthermore the invention also provides a pressure sensor, an altimeter, an electronic apparatus, and a moving object with the electronic device. A physical quantity sensor (1) includes: a substrate (2); a piezoresistive element (5) which is disposed on the side of the surface on one side of the substrate (2); a wall section (60) which is disposed to surround the piezoresistive element (5) in a plan view of the substrate (2), on the side of the surface on one side of the substrate (2); via wiring (622) which is disposed on the side of the surface on one side of the substrate (2); and a covering layer (641) which is disposed away from the via wiring (622) in the plan view on the side opposite to the substrate (2) with respect to the wall section (60) and configures a cavity portion (S) along with the substrate (2) and the wall section (60).
