PROBLEM TO BE SOLVED: To reduce a use volume of gold at gold plating.SOLUTION: A given length area positioned away from a tip of a tab part 11 is to be a contact area L with a female terminal fitting F, and a first gold-plated layer 13 is formed on the surface of the contact area L, while a second gold-plated layer 14 thinner than the first gold-plated layer 13 is to be formed at an area in front of the contact area L in the tab part 11. Thus, as the first gold-plated layer 13 with a given film thickness is formed at a part where electric conduction with the female terminal fitting F is necessary, durability unchanged from the prior art is maintained, and, as film thicknesses of gold-plated layers of other sites are lowered, a use volume of gold can be reduced. |
