摘要:
A Pb-free solder includes a first metal including at least Sn and Bi, and a second metal including at least an Ni—Fe alloy. In the first metal, the sum of Sn and Bi is 90 mass % or more, and a ratio of Bi is 5 to 15 mass %. A ratio of the second metal to the sum of mass of the first metal and mass of the second metal is 5 to 30 mass %.
