摘要

A gas barrier coating having excellent gas barrier properties and transparency is prepared, the gas barrier coating having an arithmetic mean roughness (Ra) of 2.0 nm or less and having, in a range of 20 nm to 1,000 nm in a thickness direction, a composition which when expressed by SiO_xCy is within an area enclosed by the five points of A (x=0.8, y=0.8), B (x=1.2, y=0.8), C (x=1.9, y=0.1), D (x=1.9, y=0.0), and E (x=0.8, y=0.55) in an orthogonal coordinate system where x is the horizontal axis and y is the vertical axis.
