Provided is thermal spray slurry capable of forming a dense coating by thermal spraying while suppressing cracks. Thermal spray slurry includes: thermal spray particles having an average particle diameter of 1 &#x3bc;m or more and 10 &#x3bc;m or less and a dispersion medium in which the thermal spray particles are dispersed, and has a filling rate of 84 mass % or less, the filling rate being calculated by the following expression,filling rate (mass %)=&#xd7;100,

Thermal spray slurry

To provide thermal spray slurry capable of forming a thermal sprayed coating having a high adhesion strength on a thermal spray target surface of a substrate, disclosed is thermal spray slurry for forming a thermal sprayed coating on the thermal spray target surface by spraying the thermal spray slurry on the thermal spray target surface of the substrate, the thermal spray slurry containing: thermal spray particles having a 50% particle diameter D50 equal to or larger than 1 &#x3bc;m and equal to or smaller than 5 &#x3bc;m in volume-based cumulative particle diameter distribution; and a dispersion medium in which the thermal spray particles are dispersed. In addition, a ratio D10/Ra between a surface roughness Ra (unit: &#x3bc;m) of the thermal spray target surface and a 10% particle diameter D10 (unit: &#x3bc;m) of the thermal spray particles in the volume-based cumulative particle diameter distribution satisfies a formula '0.4&#x3c;D10/Ra&#x2264;0.9'.
