Abstract
In a semiconductor dynamic quantity sensor, a mass serving as a weight portion for detecting application of a dynamic quantity is divided into three masses () in series. The masses () thus divided are connected to one another by connecting beams (CB, CB, CB, CB). The masses () located at both the end portions are supported through beams (B, B, B, B) by a semiconductor substrate () so as to be allowed to be displaced in the direction orthogonal to the connection direction of the masses. The center mass () connected to the masses () through the connecting beams (CB, CB, CB, CB) is allowed to be displaced only in the connecting direction of the masses by the connecting beams (CB, CB, CB, CB).
