Abstract
An acceleration sensor includes: a rectangular moving electrode; a pair of beams which connect to centers of two opposite sides of the moving electrode, and support the moving electrode freely swingably; and first and second fixed electrodes which are provided on one side and other side of a boundary line, respectively, and are arranged to be opposed to a front surface of the moving electrode at a predetermined interval. A straight line that connects the pair of beams to each other is taken as the boundary line. Then, on a back surface of the moving electrode, first and second recessed portions are formed on one side of the boundary line and the other side thereof, respectively.
