A light-diffusing composition having an alicyclic structure-containing block copolymer and a filler, in which the alicyclic structure-containing block copolymer has a polymer block [A] containing a specific repeating unit [1] in an amount of 90% by weight or more and another polymer block [B] containing a specific repeating unit [2] and/or another specific repeating unit [3] in a total amount of 30% by weight or more and which has a flexural modulus determined by molding the composition into a plate of 2 mm in thickness and measuring at 25 ° C in accordance with ASTM-D790 of from 10,000 to 27,000 kgf/cm2. Thus, a light-diffusing composition appropriate for molded light-diffusing articles (a light-diffusing plate, etc.) which has a high light permeability, excellent light-diffusing properties and such a high mechanical strength as being hardly broken at molding or practically using is provided.
