Abstract
A physical quantity sensor includes: an angular velocity detection element; an acceleration detection element; a bonding wire through which a detection signal of the acceleration detection element propagates; and a shield unit that is located between the angular velocity detection element and the bonding wire and is connected to a fixed potential. The angular velocity detection element and the acceleration detection element are disposed to be deviated in a height direction. At least a part of the shield unit is disposed between the angular velocity detection element and the acceleration detection element.
