Abstract
An electro-strictive actuator includes an electro-strictive element having a first surface through which a mechanical displacement is output. A mechanical member has a second surface which directly contacts the first surface so that the mechanical displacement of the electro-strictive element is output without attenuation to the mechanical member. The first surface or the second surface is provided with a ditch filled with a first adhesive to adhere the electro-strictive element to the mechanical member. A portion of the side of the electro-strictive element in the vicinity of the second surface may be additionally adhered to the second surface by a second adhesive. Deletion of adhesive in the contact between the first and second flat surfaces allows a good propagation of the mechanical displacement output from the electro-strictive element to the mechanical member, while an adequate adhesion strength is achieved by the adhesive in the ditch.
