PROBLEM TO BE SOLVED: To provide a luminous molded body with which occurrence of a luminous pigment without contribution to phosphorescence emission is suppressed and with which afterglow brightness is easily heightened.SOLUTION: A first base part 12 composed of a polymeric compound is formed by injection molding, and first luminous parts 13, 14, 15 composed of a polymeric compound are laminated and stuck to a portion of the first base part 12. Because a luminous pigment can be arranged on a predetermined position for phosphorescence emission, occurrence of a luminous pigment without contribution to phosphorescence emission is suppressed. Furthermore, because the first luminous parts 13, 14, 15 are formed by injection molding, thickness of the first luminous parts 13, 14, 15 is easily increased by appropriately designing a molding die. Because afterglow brightness is heightened nearly in proportion to the thickness of the first luminous parts 13, 14, 15, afterglow brightness of a luminous molded body 10 is easily heightened. |
