摘要： A thermal barrier coating (1) includes: a metal bonding layer (11) made of an alloy containing Al; a thermal barrier layer (15); and an intermediate layer (16) provided between the metal bonding layer (11) and the thermal barrier layer (15). The thermal barrier layer (15) contains a compound represented by the following general Formula (1),
Ln x Ta y Hf z O (3x+5y+4z)/2 ... (1)
(wherein Ln is an atom of one element selected from among rare earth elements, x is 0 to 1.0, y is 0.8 to 3.0, and z is 0 to 7.0). The intermediate layer (16) contains at least one layer selected from among the following (A) to (C): (A) a layer containing hafnium oxide (HfO 2 ) as a main component; (B) a layer containing, as a main component, a compound consisting of tantalum (Ta), hafnium (Hf), and oxygen (O); and (C) a layer containing, as a main component, a compound consisting of a rare earth element, tantalum (Ta), hafnium (Hf), and oxygen (O).-
