PROBLEM TO BE SOLVED: To make a beautiful molded product in design capable of being molded to a desired shape and coping with various usage by using a light-accumulating structure including a light-accumulating material and a light-transmittable structure provided at the outside of the light-accumulating material. SOLUTION: A light-accumulating material 1 is molded into a cylinder having a bottom of a diameter of 4 mm and a height of 260 mm using ZnS:Cu- containing fluorescent plastic. A light-transmittable structure 2 is molded into a pipe shape having an outer diameter of a bottom of 10 mm, an inner diameter of 8 mm and a height of 260 mm using an acrylic resin. The light-accumulating material 1 is disposed on an inner side of the light-transmittable structure 2 and both ends of the light-accumulating material 1 and the light-transmittable structure 2 are fixed by a vinyl chloride resin to provide a light-accumulating structure 3. Each portion of 50 mm from both ends of the light-accumulating structure 2 are bent to a U shape by heating, for example, to prepare a door knob for a front door.
