The invention relates to a Ni alloy anode material for Ni electroplating,
which exhibits high plating yield. The Ni alloy anode material comprises
a Ni alloy consisting essentially of high-purity Ni having purity of
99.99 mass % or higher and, as an alloy component, Si and Al in the
following contents: Si: 30 to 300 ppm, and Al: 30 to 300 ppm.
