Two ceramic members are coated with a highly conductive metal such as silver to form an electrode, and the other is made of a thin plate-like metal material that is conductive. A metal member that forms an electrode and is held by the ceramic member; and an insulating adhesive that bonds and adheres the ceramic member and the metal member. Electrode structure of electrostrictive element. (2) The metal coating is not applied to a portion of the end face of the ceramic member included in the electrostrictive element that is held by the driven member. Electrode structure of electrostrictive element. (3) The ceramic member included in the electrostrictive element is formed to have a larger external dimension than the metal member sandwiching it, and the difference in size between the ceramic member and the metal member after bonding forms The electrostrictive device according to claims 1 to 2 of the claims registered as a utility model, characterized in that a groove is provided around the metal member, and an adhesive is used to fill the groove and swell to form a dam. Electrode structure of the element.
