An object of the present invention is to provide a barrier film having the
extremely high barrier property and the better transparency, a method for
manufacturing the same, and a laminated material, a container for
wrapping and an image displaying medium using the barrier film. According
to the present invention, there is provided a barrier film provided with
a barrier layer on at least one surface of a substrate film, wherein the
barrier layer is a silicon oxide film having an atomic ratio in a range
of Si:O:C=100:140 to 170:20 to 40, peak position of infrared-ray
absorption due to Si--O--Si stretching vibration between 1060 to 1090
cm.sup.-1, a film density in a range of 2.6 to 2.8 g/cm.sup.3, and a
distance between grains of 30 nm or shorter. Still more, there is
provided a barrier film provided with a barrier layer on at least one
surface of a substrate film, has a composition wherein the barrier layer
is a silicon oxi-nitride film, and the silicon oxi-nitride film has an
atomic ratio in a range of Si:O:N:C=100:60 to 90:60 to 90:20 to 40, a
maximum peak of infrared-ray absorption due to Si--O stretching vibration
and Si--N stretching vibration is in a range of 820 to 930 cm.sup.-1, a
film density is in a range of 2.9 to 3.2 g/cm.sup.3, and a distance
between grains is 30 nm or shorter.
