PROBLEM TO BE SOLVED: To suppress electric resistance with a moving contact low without inviting cost increase and size increase.SOLUTION: A fixed contact 1 where a moving contact 9 slides includes: a base material 3; and a plating layer 5 (tin: Sn and such). The base material 3 is composed of a plate material of stainless steel, an alloy of aluminum (Al) or copper (Cu) having an electric resistivity higher than that of the plating layer 5. |
