Summary:PROBLEM TO BE SOLVED: To provide a hard coat film that is excellent in an anti-blocking property, and is excellent in transparency, adhesion, scratch resistance, and also hardness.SOLUTION: The present invention relates to a hard coat film that is provided with a transparent base material layer: and a hard coat layer to be laminated on at least one surface of the base material layer. The hard coat film is characterized in that the hard coat layer includes at least a particle of a larger particle diameter larger than an average film thickness of the hard coat layer by 0.05 μm or more, existence density of a projection part having a height of 0.05 μm or more in a hard coat layer surface is 250×10piece/mor more, and a haze value is 0.9% or less. As a refractive index with light of 589 nm wavelength of the particle, it is preferable to be 1.35 or more and 1.75 or less. 【課題】耐ブロッキング性に優れると共に、透明性、密着性、耐擦傷性及び硬度にも優れるハードコートフィルムの提供を目的とする。【解決手段】本発明は、透明な基材層と、この基材層の少なくとも一方の面に積層されるハードコート層とを備えるハードコートフィルムであって、上記ハードコート層が、その平均膜厚より０．０５μｍ以上大きい粒子径の粒子を少なくとも含み、上記ハードコート層表面における０．０５μｍ以上の高さを有する凸部の存在密度が２５０?１０６個／ｍ２以上であり、ヘイズ値が０．９％以下であることを特徴とするハードコートフィルムである。上記粒子の波長５８９ｎｍの光の屈折率としては、１．３５以上１．７５以下が好ましい。【選択図】図１
