A method of manufacturing a laminated substrate is provided. The method includes: forming an oxide film on at least a surface of a first substrate having a hardness of equal to or more than 150 GPa in Young's modulus, and then smoothing the oxide film; implanting hydrogen ions or rare gas ions, or mixed gas ions thereof from a surface of a second substrate to form an ion-implanted layer inside the substrate, laminating the first substrate and the second substrate through at least the oxide film, and then detaching the second substrate in the ion-implanted layer to form a laminated substrate, heat-treating the laminated substrate and diffusing outwardly the oxide film.
