<P>PROBLEM TO BE SOLVED: To enable to reduce cost by improving quality while decreasing thicknesses of components one by one and making dent or the like never occur and by improving productivity in an illumination fixture into which light is made to enter from one end of the thickness of a conventional light guide plate and in which the linear light is obtained at the opposed other end. <P>SOLUTION: When increasing the thickness of the light guide plate 2, a means is taken to make a plurality of sheets of light guide plates divided from each other in the thickness direction as the necessary thickness by overlaying them, and first of all, by forming a light guide plate main body 21 and by forming light guide plate auxiliary parts 22, 23 with two-color molding method against this light guide plate main body 21, a process which takes time and effort such as adhesion is eliminated, and the overlaying is made to be completely carried out. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
