Provided is a thermal spray material which can form a thermal spray coating layer having excellent characteristics such as porosity, hardness, plasma resistance corrosivity, and the like. According to the present invention, provided is a thermal spray material which comprises rare earth element oxyhalide (RE-O-X) including a rare earth element (RE), oxygen (O), and a halogen element (X). A molar ratio of the halogen element to the rare earth element (X/RE) in the rare earth element oxyhalide is at least 1.1.
