(57) Provided are: a cement composition that retains properties as a mixing material such as improving fluidity and contributing to a strength development, said cement composition being capable of using all of the raw material fly ash obtained from a coalfired power plant, etc., without having to classify out the coarse powder, and also being capable of contributing to long-term strength development; a method for producing said cement composition; and a method for producing fly ash for a cement composition. The cement composition is characterized by including cement and fly ash, the fly ash content being 30 mass% or less, and the fly ash having a volumetric particle size distribution that satisfies formula (I). 0.24 < (D50 - D10)/(D90 - D50) ≤ 0.5 (I) (In the formula, D10, D50, and D90 respectively represent particle diameters that are equivalent to cumulative frequencies of 10%, 50%, and 90% from the small diameter side of the fly ash).
