Zusammenfassung:A composite substrate is resistant to the development of cracks, thereby not having deteriorating properties even when exposed to high-temperatures or low temperatures, and a method is provided for producing the composite substrate. The composite substrate 10 of the present invention has a supporting substrate 2, a stress relaxing interlayer 3, and an oxide single-crystal thin film 1 stacked in the listed order. The stress relaxing interlayer 3 has a thermal expansion coefficient between that of the supporting substrate 2 and that of the oxide single-crystal thin film 1.
