Abstract
An acceleration sensor includes a base having an XY-substrate surface which is parallel to an XY plane, a beam portion having a frame shape which is arranged in a floating state above the XY-substrate surface of the base, a beam-supporting fixed portion which supports the beam on the base via supporting units like a beam supported by its both ends, weight portionswhich are arranged so as to float above the XY-substrate surface of the base, and connecting portions which support the weight portionsto the beam portion in a cantilever manner. The weight portions are displaceable in the X-axis direction, the Y-axis direction, and the Z-axis direction by the bending deformation of the frame-shaped beam portion. The beam portion is provided with an X-axis direction acceleration detecting portion, a Y-axis direction acceleration detecting portion, and a Z-axis direction acceleration detecting portion.
