A stretched film comprised of a“B1”layer comprised of a thermoplastic resin 1, an“A”layer comprised of a styrene-based resin, and a“B2”layer comprised of a thermoplastic resin 2 stacked in that order and having a width of over 1000 mm, wherein a ratio of the“A”layer in the stretched film is 45 wt % or less, an average value of an orientation angleθwith respect to a width direction across at least 1000 mm of the width direction is 0°±1°, a variation in orientation angleθis 0.5° or less, and a value of an Nz coefficient is−3.5 to−0.5 in range. |
