[Solution] This hard coating film comprises: a substrate; and a hard coating layer disposed on one main surface of the substrate. In a mandrel bending test based on JIS K 5600-5-1, using a cylindrical mandrel bending tester, where the substrate-side surface of the hard coating film is in contact with a mandrel, and the diameter of the mandrel from which cracks occur in the hard coating layer is set to D μm, and the total thickness of the hard coating film is set to α μm, the ratio D / α is 130 or less.
