Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a soundproof member capable of reducing noise in a wide frequency range from a high frequency to a low frequency when mounted on a driving device comprising a rotating body such as a motor.SOLUTION: A soundproof member 1 comprises: an elastic member 10 having a base material 12 mounted on a driving device 9 comprising a rotating body, and made of resin or elastomer and a magnetic filler 13 oriented while concatenated in the base material 12 in one direction; and a mass 11 arranged on a plane extending along the axis of rotation of the rotating body through the elastic member 10 and supported by the elastic member 10.SELECTED DRAWING: Figure 1 【課題】モータなどの回転体を備える駆動装置に装着した場合に、高周波数から低周波数までの広い周波数帯域の騒音を低減することができる防音部材を提供する。【解決手段】防音部材１は、回転体を備える駆動装置９に装着され、樹脂またはエラストマーからなる母材１２と、母材１２中に一方向に連接して配向している磁性フィラー１３と、有する弾性部材１０と、該回転体の回転軸方向に延在する面に弾性部材１０を介して配置され弾性部材１０に支持されるマス１１と、を備える。【選択図】図１
