A physical quantity sensor comprising:

• an element piece including a movable weight and movable electrode portions which are provided to extend from the movable weight;
• fixed electrode portions which are provided in a first direction in which the element piece is displaced, with a gap d1 interposed therebetween;
• and
• fixed portions which are provided to face an end portion of the element piece,
• wherein a recess is provided on an end portion of the movable weight in a position facing the fixed portions,
• the recess extends from an end of the movable weight into the movable weight along an axis through the center of the movable weight,
• a first stopper portion which extends towards the movable weight is provided on the fixed portion, and
• a tip end of the first stopper portion is inserted into the recess, and a gap d2 between the tip end and the movable weight is narrower than the gap d1.
