To provide an easily tearable laminated film having retort resistance and excellent strength and excellent in manual tearability or the like.

The easily tearable laminated film comprises at least three layers, that is, a polyester biaxially stretched film layer (X) of which the extinction angle (inclination of a main axis) is not more than 30°, a polyamide biaxially stretched film layer (Y) having an inorganic thin film layer, of which the extinction angle (inclination of a main axis) is not more than 30°, formed to at least one surface thereof and a sealant layer (Z). The easily tearable bag is obtained by thermally fusion-bonding the mutual sealant layers of the laminated film.
