Zusammenfassung:Provided are a coated member in which damage of a coating film can be suppressed in a high temperature environment and the coating may be performed at low cost, and a method of manufacturing the same. A coated member includes a bond coat and a top coat sequentially laminated on a substrate made of a Si-based ceramic or a SiC fiber-reinforced SiC matrix composite, wherein the top coat includes a layer composed of a mixed phase of a (Y1-aLn1a)2Si2O7 solid solution (here, Ln1 is any one of Nd, Sm, Eu, and Gd) and Y2SiO5 or a (Y1-bLn1′b)2SiO5 solid solution (here, Ln1′ is any one of Nd, Sm, Eu, and Gd), or a mixed phase of a (Y1-cLn2c)2Si2O7 solid solution (here, Ln2 is any one of Sc, Yb, and Lu) and Y2SiO5 or a (Y1-dLn2′d)2SiO5 solid solution (here, Ln2′ is any one of Sc, Yb, and Lu).
