Abstract
A physical quantity sensor includes an anchor portion, a movable portion displaceable in a height direction, a supporting portion rotatably connected to the anchor portion and the movable portion, and a detection portion. The supporting portion includes a first connection arm connecting the anchor portion and the movable portion to each other and a leg portion extending from the anchor portion in a direction opposite to the first connection arm, the leg portion being displaced in a direction opposite to a displacement direction of the movable portion when the supporting portion rotates. A stopper surface is disposed at a position to which a distal end portion of the leg portion is contactable when the leg portion is displaced in the direction opposite to the displacement direction of the movable portion. Displacement of the movable portion is restricted when the distal end portion of the leg portion contacts the stopper surface.
