<P>PROBLEM TO BE SOLVED: To provide a seamless reflection body with high use efficiency of light by repeatedly using a unit cell with reflection patterns arranged thereon to cover the reflection face. <P>SOLUTION: A unit cell 31 having been randomly arranged with reflection patterns 28a enclosed in the frame 41 is prepared and the unit cell 31 is repeatedly arranged into a matrix while leaving a proper space S. Then a plurality of reflection patterns 28b are added as randomly arranged but not overlapped in the space S between the frames 41 of the unit cells 31. Thus, the reflection patterns 28b are also arranged in the boundary regions of the frames 41 of the cells 31, so that the obtained reflection body 20 has the reflection patterns 28a and 28b uniformly and randomly arranged all over the reflection face 21. <P>COPYRIGHT: (C)2003,JPO |
