A regenerated resin composition comprising (I) a molded article pulverized material (Component A) that satisfies conditions

(1) that the molded article pulverized material is a pulverized material of a molded article having an aromatic polycarbonate resin content of 30 to 98% by weight,

(2) that the pulverized material has a viscosity average molecular weight of 17,000 to 30,000, and

(3) that the pulverized material has a wet heat retention ratio of at least 60%, and

(II) an aromatic polycarbonate resin (Component B).

According to the present invention, there is provided a regenerated resin composition that comprises a pulverized material from a molded article made of an aromatic polycarbonate resin and that is excellent in the property of retaining physical properties for a long period of time and excellent in mechanical strength.
