PROBLEM TO BE SOLVED: To provide a polishing film of bonded abrasive-grain type capable of finish polishing of a surface of a precision part with high smoothness, by forming mesh crack taking in polishing trash produced during polishing on a surface of the film, and a manufacturing method therefor. SOLUTION: In a polishing film 10, cerium oxide particle 13 having an average particle diameter in the range of 5 to 50 nm or mixed particles 13, 15 containing the cerium oxide particle, having an average particle diameter in the range of 5 to 50 nm is bonded with resin binder 14, and a polishing layer 12 on the surface of which the mesh crack is formed, is formed on a surface of a base film 11.
