To provide a thermal spray material capable of forming a dense coating.SOLUTION: A mixture is obtained by mixing a ceramic or metal fine particle with an average particle size of 1 μm or more and 10 μm or less, and a liquid state thermoset resin, the fine particle being evenly dispersed (step S11). The mixture is hardened by heating (step S12), and a hardened product is crashed into a particle with a particle size larger than that of the fine particle (step S13). This provides a thermal spray material capable of forming a dense coating by a plasma spray, a frame spray or laser spray.SELECTED DRAWING: Figure 2 【課題】緻密な被膜を形成することが可能な溶射材料を提供する。【解決手段】平均粒径が１μｍよりも大きく、かつ、１０μｍ以下であるセラミックスまたは金属の微粒子と、液状の熱硬化性樹脂とを混合することにより、微粒子が均一に分散した混合物が得られる（ステップＳ１１）。混合物は加熱により硬化され（ステップＳ１２）、硬化物は、微粒子よりも粒径が大きい粒子に粉砕される（ステップＳ１３）。これにより、プラズマ溶射、フレーム溶射またはレーザ溶射において、緻密な被膜を形成することが可能な溶射材料が得られる。【選択図】図２
