Claim Text:
1. A composite plating liquid comprising: a plating metal salt including a halide salt, wherein the halide salt includes nickel bromide; a sulfate of at least one element selected from alkali metals and alkaline earth metals; boric acid; carbon nanotubes; and a dispersant, wherein the dispersant is polyacrylic acid, wherein a metal of the plating metal salt comprises nickel, wherein a concentration of the plating metal salt is 10 to 100 g/L, and a concentration of the sulfate is 200 to 500 g/L, wherein a concentration of the carbon nanotubes is such that, when the composite plating liquid is made into a composite plating film by plating the composite plating liquid on a member, a weight percent of the carbon nanotubes in the composite plating film is 0.1 to 10 wt %, and wherein a weight ratio between a metal of the plating metal salt and the boric acid is in a range of 1:1 to 1:5.
