Abstract: A silicon resin (7) is applied to the outer wall (1b) of the transition piece (1) subjected to the thermal barrier coating by caulking the cooling holes (2a) provided in the inner wall (1a) by a resin (4). Then, the transition piece (1) is heated in an atmosphere furnace in order to burn or decompose the resin (4). A part of the silicon resin (7) applied to the outer wall (1b) of the transition piece (1) is decomposed or evaporated by the heating to be discharged to the atmosphere in the furnace, but a part of the silicon resin (7) remains and protects the outer wall (1b).

Accordingly, it is possible to remarkably reduce the time required to improve an external appearance of the transition piece (1) after the ashing process for the transition piece (1).
