PROBLEM TO BE SOLVED: To provide a luminous member which has a simple structure and high afterglow brightness and has a large total amount of light as the whole and emits light for a long period of time with such brightness that it is visible.SOLUTION: The luminous member includes: a plurality of luminous body parts which involve luminous bodies including luminous body particles and are regularly juxtaposed at intervals in a direction substantially orthogonal to one irradiation direction of incident light and are arranged like a layer substantially as the whole; and light-transmissive light distributing/collecting parts which are disposed between adjacent luminous bodies and distribute the radiated incident light to guide it to the luminous body parts and collect emission light emitted from the luminous bodies to emit it to the outside. |
