ABSTRACT:
A physical quantity sensor detects a physical quantity. The sensor includes a movable portion having a bottom and a protrusion disposed on the bottom of the movable portion. The protrusion is provided without adding a manufacturing process, so that a manufacturing cost is reduced. Preferably, the protrusion is provided by a remaining portion, which remains without being etched when the movable portion is prepared by etching.
