A laminated film having a resin layer laminated on at least one surface of a base film. The laminated film is characterized by: the base film being a semi-aromatic polyamide film that has been at least uniaxially stretched; the resin layer containing fine particles; the thermal shrinkage factor in the longitudinal direction Sand the thermal shrinkage factor in the width direction Sof the film measured under conditions of 250° C.×5 minutes each being −1.0 to 1.5%; the tensile elongations at break in the longitudinal direction and in the width direction each being 70% or more; and the haze being 3% or less.

Laminated film and method for manufacturing same

Provided is a semiaromatic polyamide fil having an average linear expansion coefficient in the width direction, measured under conditions of 20 to 125° C., of −90 to 0 ppm/° C.
