<p><P>PROBLEM TO BE SOLVED: To provide a reflector for minimizing depth of reflection materials accumulated at a bottom so as to enhance reflectivity. <P>SOLUTION: A reflector 1 comprises a basis material having a reflective layer 30 formed on a surface 10a thereof, and a triangular pyramid trapezoidal recessed portion 20 is formed on the surface 10a, which includes three side faces 22 orthogonal to each other and a bottom face 23. In addition, a trapezoidal recessed portion can be formed, which includes two side faces and two bottom faces, and the side faces are arranged each other at a right angle. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
