    • PROBLEM TO BE SOLVED: To provide a fluidity improver improving the melt fluidity of an aromatic polycarbonate resin composition and chemical resistance of a molded product without deteriorating heat, peeling and impact resistances, transparency, etc., of the molded product of the aromatic polycarbonate resin.
      SOLUTION: The aromatic polycarbonate resin composition is prepared by compounding 92.5 pts.mass of the aromatic polycarbonate resin with 7.5 pts.mass of the fluidity improver. In the resin composition, the fluidity improver satisfying the relationships of the absolute value of (n
      PC -n
      P )≤0.01, 0.01 μm≤dv≤0.3 μm and SPL≥1.2 L
      PC (wherein, n
      PC is the refractive index of the aromatic polycarbonate resin; n
      P is the refractive index of the fluidity improver; dv is the volume-average domain diameter of the fluidity improver dispersed in a matrix of the aromatic polycarbonate resin; SPL is the spiral flow length of the resin composition; and L
      PC is the spiral flow length of the aromatic polycarbonate resin) is used.
