PROBLEM TO BE SOLVED: To provide a lead frame together with its manufacturing method for effective use of palladium and improved work speed. SOLUTION: A tape material 10A with a pre-formed opening is pasted to regions corresponding to a surface tip-end part 3A of a inner lead part 3 and front/rear surface of an outer lead part 4, which is submerged in a palladium molten plating bath, so that a partial plating coat of palladium is formed at the surface tip-end part 3A of the inner lead part 3 and the front/rear surface of the outer lead part 4 at the same time. Thus, effective use of palladium is encouraged while efficiency of partial plating work is raised. |
