The present invention provides an oxidation-resistant coating having superior oxidation resistance and superior ductility and toughness for long-term use, and a method for forming the oxidation-resistant coating. An MCrAlY layer primarily containing an MCrA1Y alloy (in which M indicates at least one element of Co and Ni) is formed on a substrate formed of a heat-resistant metal by thermal spraying or EB=VD, and subsequently, aluminum is diffused into a part of the MCrAlY layer in the thickness direction thereof from a side opposite to the substrate.
