Abstract
An electrically-conductive material containing Ag in an amount of 10 mass % or more and 70 mass % or less, Pd in an amount of 30 mass % or more and 90 mass % or less, Ni in an amount of more than 5 mass % and 45 mass % or less, and inevitable impurities. A ratio of a Ni content (mass %) to a Ag content (mass %) (Ni (mass %)/Ag (mass %)) is 0.1 or more and 5.0 or less, metal structures include a AgPd alloy phase and a PdNi alloy phase, and a volume ratio of the PdNi alloy phase is 18 vol % or more and 80 vol % or less. Ni is added in a high concentration to a AgPd alloy, and the amount of PdNi alloy phases generated as separate phases is controlled to strengthen the entire alloy.
