摘要：
An aromatic polyamide resin molding having a root-mean-square roughness of not less than 1.0 nm and a 10-point mean roughness of not more than 80 nm as measured on at least one surface thereof by interatomic force microscopy and a Young's modulus in tension of not less than 9.8 GPa. The molding is suitable as a film having excellent scraping resistance and evenness on the surface protrusions, particularly as a film for magnetic recording media.
