To provide an easy-to-manufacture antireflection case with sufficient antireflection effect, and its manufacturing method.SOLUTION: An antireflection uneven surface 2 for preventing reflection of visible light is formed on an inner surface of an antireflection case which is a resin molding. The antireflection uneven surface 2 has a large number of primary protrusions 21 and a large number of secondary protrusions 22 formed on surfaces of the primary protrusions 21. An average height of the primary protrusions 21 is 40 μm or more. An average aspect ratio of the primary protrusions 21 is 0.1 or more. The average height of the secondary protrusions 22 is 0.4 μm or more. The average aspect ratio of the secondary protrusions 22 is 0.6 or more.SELECTED DRAWING: Figure 2
