A Cellulose acylate film, in which X-ray diffraction intensity satisfies following formulae and a half-value width of the peak at 2θ2 is greater than 3° and not greater than 7°:
0.40≦Ic2/(Iam2+Ic2) ≦0.75;
Iam2I1+{(I3−I1)/(2θ3−2θ1)×(2θ2−2θ1)}; and
Ic2=2−Iam2,
wherein when it is assumed that θis the Bragg angle, 2θ1 and 2θ3 indicate 2θ at which the intensity becomes the minimum in the 2θ range of 4° to 5° and 14° to 16°, respectively, 2θ2 indicates 2θ at which the intensity becomes the maximum in the 2θ range of 5° to 10°, and I1, I2 and I3 indicate a diffractive intensity at 2θ1, 2θ2 and 2θ3, respectively.
