PROBLEM TO BE SOLVED: To provide a base material with a hard coating film having high transparency and high film strength by a coating film made of hollow silicon-based fine particles which has high void ratio, shows low refractive index, has high productivity, is hardly broken, and has a particle diameter of 1μm or less of a narrow particle diameter distribution or hollow silicon particle aggregate and matrix resin. SOLUTION: The base material with the hard coat film comprises the base material and a hard coat film formed on the base material, wherein the hard coat film comprises a matrix component, and a hollow silicon-based fine particle aggregate aggregating hollow silicon-based particles and having a volume average particle diameter ranging from 0.04 to 1μm.
