摘要： Provided is a coated member which is provided with a heat shielding coating layer that exhibits excellent characteristics in a high temperature environment in which water vapor is present. A coated member (100) which is provided with a heat shielding coating layer (102) that is composed of a zirconia-dispersed silicate wherein ZrO 2 stabilized by Yb 2 O 3 is precipitated as dispersed phases in a matrix that is a rare earth disilicate, a rare earth monosilicate or a mixed phase of a rare earth disilicate and a rare earth monosilicate. The rare earth disilicate is a (Y 1-a [Ln 1a ) 2 Si 2 O 7 solid solution (wherein Ln 1 is Sc, Yb or Lu) or a (Y 1-c [Ln 2 ] c ) 2 Si 2 O 7 solid solution (wherein Ln 2 is Nd, Sm, Eu or Gd); and the rare earth monosilicate is Y 2 SiO 5 , [Ln 1 '] 2 SiO 5 , a (Y 1-b [Ln 1 '] b ) 2 SiO 5 solid solution (wherein Ln 1 ' is Sc, Yb or Lu) or a (Y 1-d [Ln 2 '] d ) 2 SiO 5 solid solution (wherein Ln 2 ' is Nd, Sm, Eu or Gd).
