Physical Quantity Sensor

Abstract

A physical quantity sensor includes: a base part; a plate-shaped cantilever including a hinge part and a movable part coupled to the base part via the hinge part, the movable part being displaced in relation to the base part with the hinge part serving as a fulcrum; and a physical quantity detection element fixed to the base part and the movable part over the hinge part. The movable part is longer than the hinge part in a second direction intersecting a first direction in which the hinge part and the movable part are arranged when viewed in a plan view of the cantilever, and a free end of the movable part located on a side opposite to the hinge part coincides with an end of the physical quantity detection element on the free end side or is located closer to the hinge part side than the end when viewed in a plan view of the cantilever.
