There is provided a cellulose acylate film including a core layer and a skin layer, in which a mixed layer is formed between the core layer and the skin layer, wherein a cellulose acylate included in the core layer has an average acyl substitution degree S2 of 2.00 to 2.55, a cellulose acylate included in the skin layer has an average acyl substitution degree S3 of 2.60 to 2.95, and an average acyl substitution degree S1 of the cellulose acylate of the mixed layer satisfies Equation (A1), and the mixed layer has a thickness of 100 nm to 300 nm: Equation (A1): S2+0.05×(S3−S2)
