Claim 0:
1. A substrate joined body comprising:
a first substrate;
a second substrate;
an organic film that comprises silicon and carbon, and the organic film joins the first substrate and the second substrate; and
a protective film that comprises an inorganic element, and the protective film is formed over the organic film from at least a part of a surface of the first substrate and at least a part of a surface of the second substrate,
wherein the organic film comprises a region in which a ratio of carbon to silicon based on atomic percentage is from 0.0 to 5.0 in a region within 50 nm in a thickness direction from a surface of the organic film on a side of the protective film, when the surface is measured by X-ray photoelectron spectroscopy.
