PROBLEM TO BE SOLVED: To increase corrosion resistance of a metallic plate forming a sealing member by an inexpensive means. SOLUTION: Corrosion resistance of the metallic plate 5a of a contact seal 5 as the sealing member formed by the metallic plate 5a and rubber 5b is increased by forming the metallic plate 5a by a hot dipping steel plate having a plated layer A formed by Zn-6%Al-3%Mg alloy by the inexpensive means.
