Gas sensor
An insulator, airtightly supported via an annular metallic packing on a cylindrical housing, has a small-diameter portion and a large-diameter portion. A tapered surface extends in a radially outer direction from a small-diameter cylindrical surface to a large-diameter cylindrical surface. A receiving surface, formed on an inside wall of the housing, supports the tapered surface via the metallic packing. The tapered surface is brought into line contact with the metallic packing at its outer or inner circumferential portion.
