ABSTRACT:
An insulating frame is formed by an insert mold such that a portion of a stator lead member is exposed from and flush with the upper surface thereof. The exposed portion of the stator lead member is plated with a metal having a low melting temperature, and the upper surface of the insulating frame is coated with an adhesive. Then, a ceramic dielectric body, which is provided at its lower side with a stator electrode, is placed on the adhesive layer. Subsequently, heat is applied to the ceramic dielectric body and the insulating frame while pressing them to each other so that the metal of the low melting point is molten to electrically connect the stator electrode and the stator lead member. The assembly is then cooled to solidify the metal of the low melting point, as well as the adhesive. Since the ceramic dielectric body is fixed to the frame by means of the adhesive, the steps of grinding and polishing of the stator electrode is eliminated advantageously.
