The present invention is to provide a polyamide laminated film comprising a resin layer A and a resin layer B formed on at least one surface of the resin layer A,the resin layer A being composed mainly of a m-xylylene group-containing polyamide polymer (a-1) which is one prepared from monomer components containing a xylylenediamine compound as a main diamine component and an alpha,omega-aliphatic dicarboxylic acid having from 6 to 12 carbon atoms as a main dicarboxylic acid component, the xylylenediamine compound being m-xylylenediamine alone or a mixture of m-xylylenediamine and p-xylylenediamine, andthe resin layer B being mainly composed of a mixed polymer (b-3) which is a mixture of from 99 to 80% by weight of an aliphatic polyamide (b-1) and from 1 to 20% by weight of an elastomer (b-2).The laminated film is good in a gas barrier property and also in a flexural fatigue resistance and a transparency.
