Abstract
A magnetic-thin-film-equipped substrate includes a substrate and a magnetic thin film. A difference obtainable by subtracting a first internal stress of the magnetic thin film from a second internal stress of the magnetic thin film is 50 MPa or more. The first internal stress is an internal stress of the magnetic thin film in a first direction along a surface of the magnetic thin film extending in parallel with the substrate. The second internal stress is the internal stress of the magnetic thin film in a second direction parallel to the surface and perpendicular to the first direction.
