The present invention provides an optical information medium in which the recording and/or reproducing beam incident side surface displays excellent anti-staining properties and lubricity, as well as superior scratch resistance and abrasion resistance. An optical information medium comprising a film element composed of one or more layers including at least a recording layer ( 4 ) or a reflective layer, on a supporting substrate ( 20 ), wherein at least one of the supporting substrate ( 20 )-side surface and the film element-side surface is formed of a hard coat layer ( 8 ) comprising a cured product of the hard coat agent composition comprising a fluorine-containing block copolymer (A) and an active energy ray-curable compound (B).
