A mechanical quantity detecting element includes a main frame displaceably supported with respect to a substrate in an X axis direction parallel to a surface of the substrate, a transducer displaceably supported with respect to the main frame in a Y axis direction perpendicular to the X axis direction and parallel to the surface of the substrate, and a plurality of drive electrode portions which are provided on the main frame and drive the main frame in the X axis direction. The main frame includes a terminal portion where an end of the main frame extends in the Y axis direction, and at least one of the plurality of drive electrode portions is arranged on each side in the X axis direction of the terminal portion.
