摘要： 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.

摘要： The present disclosure relates to an electrode for measuring an analyte. The electrode includes a first base layer, a first electrode layer upon the first base layer, and a second base layer. The first electrode layer is arranged between the first base layer and the second base layer. The first base layer includes a conductive metal, a conductive metal alloy, or carbon. The first electrode layer includes ruthenium metal, a ruthenium based metal alloy, nickel metal, or a nickel based metal alloy. The first base layer is made of different elements than the first electrode layer. The first base layer is more conductive than the first electrode layer.

摘要： A spark plug having a center electrode that includes a columnar noble metal tip at one end thereof, and a ground electrode that forms a spark gap between the ground electrode and a circular discharge surface of the tip. In the tip, a mass % of Pt is largest and a content percentage of Ni is more than or equal to 0 mass % and less than or equal to 40 mass %. In each of both a cross-section of the noble metal tip parallel to the discharge surface and a cross-section of the tip perpendicular to the discharge surface, particles each having an aspect ratio of more than or equal to 1 and less than or equal to 10 occupy more than or equal to 70% of observed particles in an area extending from an outline of the cross-section by a distance of 10% of a diameter of the discharge surface.
