Abstract

　振動アクチュエータを小型化する。 　駆動信号により励振される電気機械変換素子１３と、電気機械変換素子１３が接合され、その励振により駆動面に振動波を生じる弾性体１２と、弾性体１２の駆動面に加圧接触され、その振動波によって駆動される相対移動部材１５とを備える振動アクチュエータであって、弾性体１２と接合される電気機械変換素子１３の接合面１３ａは、電極が形成されている電極部１３１と、弾性体１２と電気機械変換素子１３との接着強度を向上させる接着強度向上部１３３とを有し、接着強度向上部１３３を通り、かつ、弾性体１２と相対移動部材１５との相対移動方向に直交する仮想直線Ｌが通る接合面１３ａの２つの端部のうちの少なくとも一方には、電極部１３１が形成されている振動アクチュエータ１０とした。
