A gas barrier film includes a resin substrate and an oxygen barrier coating film in contact with a first surface of the resin substrate. The resin substrate includes two or more resin layers including a base layer. Of the two or more resin layers, a resin layer forming the first surface of the resin substrate does not contain an anti-blocking agent.

A gas barrier film including a substrate film containing a resin, and a gas barrier layer that has oxygen barrier properties and is in contact with at least one surface of the substrate film, a surface of the gas barrier layer has a flat portion, and a plurality of protrusions that protrude from the flat portion. The number of protrusions that satisfy the following formula (1) is 0 to 200 per mm.sup.2, and the number of protrusions that satisfy the following formula (2) is 20 or more per mm.sup.2: d×2≤f (1); and 0.2≤f<d×2 (2), where d represents a thickness (μm) of the gas barrier layer, and f represents a height (μm) of each of the plurality of protrusions.
