A roll of a gas barrier film may be obtained by winding a gas barrier film including a base and a gas barrier layer in a direction orthogonal to a width of the film. The gas barrier layer may contain silicon, oxygen, and carbon atoms. A surface of the base, opposite to a side of the gas barrier layer, may have protrusions A having a height of 10 nm or more and less than 100 nm from a roughness center plane at a density of 500 to 10,000/mm2, and protrusions B having a height of 100 nm or more from a roughness center plane at a density of 0 to 500/mm2. The base may have a haze of 1% or less measured in accordance with JIS K-7136. A flatness index defined as the number of sites raised 1 mm or more is within a range of from 0 to 5. |
