Summary:PROBLEM TO BE SOLVED: To provide a polyamide film as an optical member excellent in transparency, heat resistance, low linear expansion, adhesion to organic/inorganic material, or low optical anisotropy.SOLUTION: The polyamide includes a structural unit A represented by the general formula (I), and a structural unit B selected from the group consisting of structural units represented by the general formula (II) or the like. In the formula (I), R1 represents a divalent aromatic group. In the formula (II), R2 represents a divalent organic group, R5 represents -O- or a divalent aromatic group, and R6 represents a divalent aromatic group.
