Claims

[Scope of utility model registration request]

In an electrostrictive effect element in which a laminate in which piezoelectric ceramic members and internal electrode conductors are alternately laminated is sealed with a metal case and a metal member, a comb-toothed spring at the tip contacts the external electrode conductor of the laminate on the side surface of the metal case. An electrostrictive effect element characterized by having lead terminals that are electrically connected by pressure.
