A non-crystalline polyester resin composition of the present invention is excellent in processing properties of its molding, mechanical properties and chemical properties, in addition to its moldability, and is used in a variety of fields, which comprises 50 to 99% by weight of a non-crystalline polyester resin (component A) and 1 to 50% by weight of an epoxy-modified block copolymer (component B), total amount of the components A and B being 100, component B being obtained by epoxidation of a block copolymer (B3) comprising a polymer block (B1) containing mainly a unit based on a vinyl aromatic compound and a polymer block (B2) containing mainly a unit based on a conjugated diene compound, an epoxy equivalent of the component B being in the range of 400 to 7,500, and an absolute difference-value of the refractive index between the components A and B being 0.008 or less.
