    摘要: A foamed sheet for reflectors which can be thermoformed into reflectors having desired shapes. A foamed sheet (A) for reflectors, characterized by being constituted of a foamed sheet (1) of a polypropylene resin which has a mean cell diameter of 50 to 650mum and at least one uneven surface (12) formed by cells (11) present in the neighborhood of the surface and a non-foamed sheet (3) of the polypropylene resin which is united with the sheet (1) by lamination in such a way that the sheet (3) lies on the sheet (1) along the uneven surface (12) to form an uneven surface (31), by containing an inorganic filler (2) in an amount of 50 to 200g/m 2, the whole or part of which filler is contained in the sheet (1), and by having a difference in refractive index of 1.0 or above between the inorganic filler (2) and the polypropylene resin, a thickness of the sheet (A) of 0.2 to 2.0mm, and a light reflectance of 97% or above.
