PROBLEM TO BE SOLVED: To inform of a luminescence to a remote place by using a light accumulation molding made of a resin containing a light accumulation pigment which can increase the amount of luminescence without increasing the content of the pigment. SOLUTION: In the light accumulation molding 10 prepared by molding the resin containing a light accumulation pigment in order to inform of a luminescence to a remote place in the luminescence direction R, a luminescent surface 16 emitting light in the luminescence direction R is formed so as to have on a periodically uneven surface wherein recesses 12 and projections 14 are arranged alternately and repeatedly. The light accumulation molding can inform of the luminescence to a remoter place as compared with a light accumulation molding having a flat luminescent surface. COPYRIGHT: (C)2009,JPO&INPIT
