PROBLEM TO BE SOLVED: To provide a multilayered laminated stretched film excellent in selective reflectivity of light, taking-up properties and film forming properties. SOLUTION: A layer (A-layer) comprising polyethylene-2,6-naphthalate containing 0.001-0.5 wt.% of inert particles with a mean particle size of 0.01-2μm and a layer (B-layer) comprising syndiotactic polyethylene are alternately laminated so as to become 11 layers or more in total and each of the A- and B-layers has a thickness of 0.05-0.3μm and the laminated film comprising these layers is stretched at least in a uniaxial direction.
