(해결 수단) 본 발명의 반사 방지 필름은, 투명 기재와, 그 투명 기재로부터 순서대로, 밀착층과, 제 1 Nb2O5 층과, 제 1 SiO2 층과, 제 2 Nb2O5 층과, 제 2 SiO2 층과, 방오층을 이 순서로 갖고, 제 1 Nb2O5 층의 광학 막두께가 28 ㎚ ∼ 33 ㎚ 이고, 제 1 SiO2 층의 광학 막두께가, 43 ㎚ ∼ 57 ㎚ 이고, 제 2 Nb2O5 층의 광학 막두께가, 264 ㎚ ∼ 288 ㎚ 이고, 제 2 SiO2 층의 광학 막두께가, 113 ㎚ ∼ 129 ㎚ 이다. To provide an antireflection film having excellent reflection characteristics (low reflectivity) in a broad band, with suppressed coloring. An antireflection film comprises a transparent base material, and an adhesive layer, a first Nb2O5 layer, a first SiO2 layer, a second Nb2O5 layer, a second SiO2 layer, and an antifouling layer in this order from the transparent base material. The first Nb2O5 layer has an optical film thickness of 28 nm to 33 nm, the first SiO2 layer has an optical film thickness of 43 nm to 57 nm, the second Nb2O5 layer has an optical layer thickness of 264 nm to 288 nm, and the second SiO2 layer has an optical film thickness of 113 nm to 129 nm.
