Contact pieces are accommodated respectively in contact housings in a main body portion. Each of the contact pieces has an intermediate portion extending between a contact portion and a terminal portion and force-fitted and held as a first discharge electrode portion in first positioning grooves. An arcuate grounding conductor is disposed on the main body portion and has integral second discharge electrode portions and dust-prevention lug portions. The second discharge electrode portions are held in confronting and spaced relation to the first discharge electrode portions via discharge gap holes formed in a side wall portion of the main body and are force-fitted and held in second positioning grooves. The first and second discharge electrode portions define discharge gaps therebetween. The first and second discharge electrode portions, inner wall surfaces of the discharge gap holes, and the dust-prevention lug portions define discharge gap chambers with the discharge gaps contained therein, the discharge gap chambers being isolated from the exterior.
