PURPOSE:To ensure the connection of an electrode, etc. by providing a projecting part at one end of the main body of an electrode and the recessed part which fits to this projecting part at the other end and by coating an anaerobic adhesive at least at one part of these projecting and recessed parts. CONSTITUTION:The projecting part 2 of conical shape with flat head is provided at one end of the main body 1 of an electrode and the recessed part 3 corresponding to the projecting part 2 is formed at the other end. A copper plating part 4 is formed on the outer surface of the electrode main body 1 in continuation from the root part 5 of the projecting part 2 upto the open hole part 6 of the recessed part 3 moreover. An anaerobic adhesive 7 is coated on the surface of the projecting part 2 and inner surface of the recessed part 3, then. The electrode 1 is connected via the uneven parts 2, 3. The plating part 5 of the projecting part 2 and plating part 6 of the recessed part 3 are electrically connected and the uneven parts 2, 3 are mechanically connected firmly by the adhesive 7. In this way, the connection of the electrode 1 is ensured and the falling and scattering of the connection part are eliminated as well.
