Abstract
An acceleration sensor includes: a semiconductor substrate that includes a support substrate and a semiconductor layer; a first-direction movable electrode; a second-direction movable electrode; a first-direction fixed electrode; a second-direction fixed electrode; and a support member. The acceleration sensor is configured to detect acceleration in a first direction in the surface direction of the semiconductor substrate and acceleration in a second direction orthogonal to the first direction and parallel to the surface direction. The first-direction movable electrode and the first-direction fixed electrode are provided such that an angle formed by an extended direction of the first-direction movable electrode and the first-direction fixed electrode and the second direction is sin(d/L)[deg], and the second-direction movable electrode and the second-direction fixed electrode are provided such that an angle formed by an extended direction of the second-direction movable electrode and the second-direction fixed electrode and the first direction is sin(d/L)[deg].
