PROBLEM TO BE SOLVED: To solve the problems wherein a conventional electromechanical transducer having a weight part and a flexible part is easily broken when receiving a strong acceleration, if the flexible part is constituted narrowly and thinly in order to heighten sensitivity. SOLUTION: This electric transducer has a constitution wherein a fixed part and a working part are connected together though the flexible part, and the working part has the weight part. The weight part has the first weight comprising a material having a light specific gravity and the second weight comprising a material having a heavier specific gravity than the first weight. The first weight is provided in contact with the working part, and the second weight is provided in contact with the first weight separately from the working part. By this constitution, even if the total weight of the weight part is light, since the center of gravity of the weight part can be generated separately from a rotation shaft of the working part, detection sensitivity can be improved.
