A casting mold material used when casting a metal material includes, as a composition: Cr within a range of 0.3 mass% or more and 0.7 mass% or less; Zr within a range of 0.025 mass% or more and 0.15 mass% or less; Sn within a range of 0.005 mass% or more and 0.04 mass% or less; P within a range of 0.005 mass% or more and 0.03 mass% or less; and a balance consisting of Cu and inevitable impurities, in which a Zr content [Zr] (mass%) and a P content [P] (mass%) have a relationship of [Zr]/[P] ≥ 5, and a Sn content [Sn] (mass%) and a P content [P] (mass%) have a relationship of [Sn]/[P] ≤ 5.
