<P>PROBLEM TO BE SOLVED: To provide a reflector in which the regularly reflected light does not converge near a light source and the drop of brightness is little even in a part distant from the light source. <P>SOLUTION: The laminated light reflector is formed by laminating resin layers consisting of an aromatic polycarbonate on both surfaces of a light reflecting layer obtained by mixing at least a white pigment in an aromatic polycarbonate and making an integrated shape. At least one of the resin layers is a transparent layer, the transparent layer has the surface roughness defined in the formulas (1) and (2) mentioned below, and the total reflection of the transparent layer side is ≥90%. The above formulas are: 10 μm≤Rc≤200 μm (1) and 20≤(Rc/RSm) (2), wherein Rc is an arithmetic average height (μm) in the surface roughness and RSm is an arithmetic average width (μm) in the surface roughness. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
