Abstract: To provide powder for thermal spraying, a method of thermal spraying, and a thermally sprayed coating, which can efficiently work supplying of a dry state powder by using a powder supplying apparatus with a thermal spraying apparatus, and which prevent variation and pulsation or lowering of supplied amount of powder and achieve a required film forming rate, and can obtain a denser coating on the surface of the substrate to be thermally sprayed. [Solution] Powder for thermal spraying 1 is a powder mixture obtained by mixing ceramic powder A whose particle diameter is D 1 and ceramic powder B whose particle diameter is D 2 , wherein D 1 is 0.5 to 12 μπι as a median diameter, D 2 is 0.003 to 0.100 μιη as an average particle diameter converted from the BET specific surface area, and when, in the powder mixture, the total weight of the ceramic powder A to be used whose prescribed particle diameter D 1 is W 1 , and the total weight of the ceramic powder B to be added to the ceramic powder A is W2, an addition ratio Y of the ceramic powder B defined by Y = W 2 / (W 1 + W 2 ) satisfies: Y ≥ 0.2066 x D 1 -0.751 and Y ≤ 0.505 x D 1 -0.163 .
