Abstract

An electric contact member comprising a thin sheet of a stainless steel and a projection of a tin-lead type solder formed on the surface of the thin sheet as a contacting portion is provided. The electric contact member is made by a process wherein a stainless steel sheet is printed with a resist paint of a desired pattern, the stainless steel sheet is optionally electroplated with nickel, the nickel-plated or non-plated stainless steel sheet is electroplated with gold, silver, palladium or their alloys, the electroplated stainless steel sheet is dipped in a bath of a tin-lead alloy solder melt whereby spot-like or stripe projections of the solder are formed on the stainless steel sheet, and then, the sheet is cut into electric contact members.
