PROBLEM TO BE SOLVED: To provide a heat resistant covered member capable of keeping the heat shielding function over a long period by efficiently suppressing the crack or fracture of a ceramic covering layer in the use under high temp, environment. SOLUTION: In the heat resistant covering member having the ceramic covering layer 3 formed with a metallic bonding layer 2 composed of at least one kind selected from among Ni, Co, Fe, Cr on a base material 1 composed of a Ni based alloy or a Co based alloy, the ceramic covering layer 3 contains at least a stabilized zirconia 4 stabilized by a rare earth element and a calcium compound 5 dispersed in the stabilized zirconia 4. |
