Reflecting sheet

Abstract

A reflecting sheet of the invention includes at least a surface layer portion and an inner layer portion, where the surface layer portion contains at least 0.3 g/m2 to 20 g/m2 of an inorganic powder and a polyolefin resin (C), the inner layer portion contains a polyolefin resin (A) and at least one kind of resins (B) incompatible with the polyolefin resin (A) at temperatures enabling stretching of the polyolefin resin(A), the surface layer portion meets (n1−n2)/n2≧0.20 (n1: refractive index of the inorganic powder, n2: refractive index of the polyolefin resin (C)), and the inner layer portion has voids.
