Abstract
A physical quantity sensor includes a package, a circuit chip disposed and held in the package, a sensor chip stacked and fixed on the circuit chip, and a wiring member having flexibility, through which the circuit chip and the package are electrically and mechanically bonded together. In the physical quantity sensor, unwanted external vibrations transmitted to the sensor chip are reduced without an external vibration dumping system such as a rubber pad, because the wiring member weakens the vibrations.
