Zusammenfassung:	An angular acceleration sensor includes a flat plate surface, a fixed portion, a weight portion, and a beam portion. The weight portion includes a recessed portion that is recessed in an X-axis negative direction in the flat plate surface. The fixed portion includes a projecting portion projecting in the X-axis negative direction in the flat plate surface to be opposed to the recessed portion, and a slit extending inward in an X-axis positive direction from a position adjacent to the projecting portion. The beam portion extends along the Y-axis in the flat plate surface, is connected between the recessed portion and the projecting portion, and supports the weight portion movably relative to the fixed portion.
