| abstract | PROBLEM TO BE SOLVED: To provide a high productivity, a small amount of foreign substances mainly composed of oligomers deposited on the surface after film formation, and particularly excellent in electromagnetic conversion characteristics when a metal-deposited thin film type magnetic recording medium is used, and a dropout. To provide a polyester film with a small amount. SOLUTION: One surface of a layer A made of a polyester resin having an intrinsic viscosity of 0.55 or more has an average particle diameter of 10 to 50. nm and a continuous film C containing 0.5 to 30% by weight of inert particles C having a volume shape factor of 0.1 to π / 6, and a film surface roughness WRa on the film C side of 0.1 to 30% by weight. 4n m, and the number of foreign substances deposited on the film C when the film is held at 120 ° C. for 30 minutes is 1,000 / mm 2. A polyester film characterized by the following. |
