The first tubular member has a flange portion at one end thereof while the second tubular member has a cap portion which accommodates the flange portion of the first tubular member with the gap being formed between the cap and flange portions. The insulating member disposed in the gap hermetically couples the first and second tubular members while electrically insulating them from one another.
