Each hollow portion has a shape in which a cross-section area when each hollow portion is cut at a plane that is parallel to the one surface of the base material is large on a side of the corresponding light blocking section and becomes gradually smaller with increasing distance from the corresponding light blocking section. A portion of the light transmissive material layer other than where the hollow portions are formed is a light transmitting section.
