The present invention provides a cellulose acylate film having excellent optical properties, no foreign matter and dirt, a good haze value, and sufficient tear strength. Moreover, the polarizing plate excellent in the polarization degree and durability is provided. In a cellulose acylate film produced by a solution casting film forming method, a cellulose acylate dope composition containing a polymerizable monomer and / or a polymerizable monomer having a functional group and a photopolymerization initiator is flowed. A cellulose acylate film having a thickness of 10 μm or more and less than 30 μm obtained by extending and photopolymerizing the monomer during or after drying, and a polarizing plate using the cellulose acylate film. |
