PURPOSE:To improve humidity resistance greatly and to acquire a compact electrorestrictive effect element by providing an insulating section having elasticity to an approximately central part of a metallic case. CONSTITUTION:An electrorestrictive effect element 1 is temporarily fixed with a thermosetting conductive adhesive 5 to be planted in an inside bottom of a metallic case 2. Thermosetting insulating adhesive is applied to upper and lower surfaces of an elastic insulator 4 such as rubber of a thickness of 2 to 3mm to seal the insulator 4 and a member 3. A combination of the metallic case 2, the member 3 and the insulator 4 is put in a drying furnace to cure thermosetting conductive adhesive 5 and thermosetting insulating adhesive 6. Then, an end part of a flange part 2a and an end part of the member 3 are welded by arc welding to complete hermetic seal. In the process, since an edge face electrode provided to an edge face of the battery jar effect element 1 and the metallic case 2 are connected by conductive adhesive, the metal case 2 can be used as an external electrode. |
