Abstract
In an acceleration sensor, a semiconductor layer is provided with a rod-shaped weight portion that passes through a center of a frame portion, extends in a second direction, and is connected to the frame portion through a first beam portion. A first-direction movable electrode and a second-direction movable electrode are provided on the weight portion. According to the above configuration, because a mass of the first- and second-direction movable electrodes can be applied to the vicinity of a center of the frame portion, and a rotational moment can be reduced. Thus, detection accuracy can be restrained from being reduced.
