Provided are a light-blocking member, a black resin composition, and a black resin molded article having excellent durability and solvent resistance, and the like. In a light-blocking member (1) comprising a substrate (11) and a light-blocking membrane (21) provided on at least one surface of this substrate (11), the light-blocking membrane (21) containing an ultraviolet curable resin as a binder resin and containing a black pigment as a filler dispersed in this binder resin is employed. The light-blocking membrane (21) preferably further contains photo- and/or thermal polymerization initiators. In addition, the content of the filler in the light-blocking membrane (21) is preferably 10% by mass or more and 60% by mass or less in terms of solids based on all resin components contained in the light-blocking membrane (21).
