Abstract:
1. A method of manufacturing a structure comprising the steps of: (a) forming an intermediate layer on a substrate; (b) forming a structure including a brittle material layer on said intermediate layer by at least using a spray deposition method of spraying material powder toward said substrate, on which said intermediate layer is formed, to deposit the material powder; and (c) separating said substrate from said structure, wherein: step (a) includes forming the intermediate layer having a void ratio higher than that of said brittle material layer by generating an aerosol containing ceramic powder having a first average particle diameter and spraying the aerosol toward said substrate to deposit the ceramic powder; and step (b) includes forming said brittle material layer by generating an aerosol containing ceramic powder having a second average particle diameter larger than said first average particle diameter and spraying the aerosol toward said substrate to deposit the ceramic powder.
