The present invention provides a hard coat film having excellent adhesion to a hard coat layer when a cycloolefin polymer film is used as a base material. The hard coat film of the present invention comprises a hard coat layer containing an ionizing radiation curable resin laminated on at least one surface of a cycloolefin polymer base film through a primer layer. This primer layer contains a modified polyolefin resin in which a polyolefin resin is graft-modified with an ?,?-unsaturated carboxylic acid or a derivative thereof, and a (meth)acrylic acid ester. In this modified polyolefin resin, the graft weight of the ?,?-unsaturated carboxylic acid or derivative thereof is 0.4 to 7 wt. % when the amount of the modified polyolefin resin is taken as 100 wt. %.
