PROBLEM TO BE SOLVED: To provide slurry for spray capable of forming a dense sprayed coating, while suppressing generation of a crack.SOLUTION: Slurry for spray includes spray particles having an average particle diameter of 1 μm or larger and 10 μm or smaller, and dispersant formed by dispersing spray particles, and a fill factor calculated from following formula is 84 mass% or less: fill factor (mass%)=B/A×100, where A in the formula is a mass of a cake of the spray particles formed by precipitating the spray particles in the slurry for spray by a centrifugal separation method, and B is a mass of a dry matter obtained by removing dispersant contained in the cake.SELECTED DRAWING: None
