A physical quantity sensor includes: a first substrate including a first fixed electrode portion disposed on a first base surface and a first through-hole penetrating the front and rear of the substrate; a second substrate including a second fixed electrode portion disposed on a second base surface and a second through-hole penetrating the front and rear of the substrate, the second base surface being arranged to face the first base surface; and a movable body arranged between the first substrate and the second substrate with gaps and including a movable electrode portion facing the first fixed electrode portion and the second fixed electrode portion. In the first through-hole, a first through-electrode electrically connected with the first fixed electrode portion is disposed. In the second through-hole, a second through-electrode electrically connected with the second fixed electrode portion is disposed.
