The contact portion has a first plated layer as its outermost layer and a second plated layer located under the first plated layer. The first plated layer is made of silver or silver alloy and has Vickers hardness not more than 90 Hv. The second plated layer is made of silver or silver alloy and has Vickers hardness not less than 100 Hv.
