<P>PROBLEM TO BE SOLVED: To provide a coating method of forming a coating film having excellent high temperature oxidation resistance and corrosion resistance with a simple process of a short production time and a low production cost and without causing deformation or the change of the structure of a base material. Ž<P>SOLUTION: The coating method includes: dipping an alloy base material 80 in a dispersion obtained by dispersing MCrAlY powder (in the formula, M expresses at least one element selected from Ni and Co and contains at least Ni when A is Co and at least Co when A is Ni) in an electrolyte containing A ion (A expresses Co or Ni); and by using a rotary electrode device 10 having a turnable cylindrical rotary electrode and an unwoven fabric layer 31 coating the surface of the cylindrical rotary electrode, performing electrolyzing while rolling the cylindrical rotary electrode coated with the unwoven fabric on the surface of the alloy base material; and forming a composite coated layer on the surface of the alloy base material.
