Abstract
A method for producing a solid lubricant includes steps of preparing and coating. A phosphate aqueous solution prepared by the step of preparing is an aqueous solution containing at least one of aluminum dihydrogen phosphate and magnesium dihydrogen phosphate in an amount of 0.5 to 10% by mass. A graphite material is coated with a phosphate using the phosphate aqueous solution. The graphite material is used at a ratio of 40 to 50 parts by mass based on 100 parts by mass of the aqueous solution.
