Zusammenfassung:The present disclosure provides a low-reflectivity black film having an excellently low reflectivity due to small regular reflection and small scattering reflection, and having a sufficiently high level of smoothness on its surface and a high degree of blackness. The low-reflectivity black film according to the present disclosure includes a porous black pigment having a porosity of 50 % or larger and a binder component at a volume ratio of 50:50-100:0, in which, with regard to surface roughness parameters Rt and Ra, Rt is 0.15-5 µm and Ra is 0.01-0.5 µm, an L* value is equal to or smaller than 20, and in a range of 400-700 nm, the maximum value of regular reflectivity is equal to or smaller than 0.8 %, the maximum value of scattering reflectivity is equal to or smaller than 2 %, and the maximum value of light transmittance is equal to or smaller than 5 %.
