Disclosed is a cellulose acylate film containing a compound having at least one connecting group selected from a group consisting of a bivalent connecting group denoted by —NH—(C═O)—O— and a bivalent connecting group denoted by —NH—(C═O)—NR— in which R represents a hydrogen atom or a substituent group, and at least one polar group which is a residue of a compound having a C log P value of less than or equal to 0.85 (however, an aromatic hetero ring-containing group which is a residue of a compound having a C log P value of less than or equal to 0.85 is excluded from the polar group), in which an equivalent weight U obtained as a value which is obtained by dividing a molecular weight by the number of connecting groups included in one molecule is less than or equal to 515.
