A MEMS sensor includes: a supporting portion; a movable weight portion; a connecting portion that couples the supporting portion with the movable weight portion and is elastically deformable; a first fixed electrode portion protruding from the supporting portion; and a first movable electrode portion protruding from the movable weight portion and disposed so as to face the first fixed electrode portion, wherein the movable weight portion is formed by stacking a conductive layer and an insulating layer in a first direction, plugs having a larger specific gravity than the insulating layer are embedded in the insulating layer, the conductive layer is connected to the first movable electrode portion, and one of the first fixed electrode portion and the first movable electrode portion has a first electrode portion and a second electrode portion in the first direction.
