Polycarbonate resin composition and molded body

A polycarbonate resin composition, comprising:

• (A) 100 parts by mass of a resin mixture comprising
• (A-1) a polycarbonate-polyorganosiloxane copolymer comprising, in a main chain thereof, a repeating unit represented by formula (I) and a repeating unit represented by formula (II), wherein n=30 to 55 and a content of the repeating unit represented by the formula (II) in the copolymer (A-1) ranges from 2.5 mass % to 6.0 mass %, and
• (A-2) a polycarbonate-polyoranosiloxane copolymer comprising, in a main chain thereof, a repeating unit represented by the formula (I) and a repeating unit represented by the formula (II), wherein n=80 to 120 and a content of the repeating unit represented by the formula (II) in the copolymer (A-2) ranges from 0.3 mass % to 2.1 mass %;
• and
• (B) 0.01 to 0.08 part by mass of at least one component selected from the group consisting of an alkali metal salt of an organic sulfonic acid and an alkali earth metal salt of an organic sulfonic acid:
• wherein:
• R1 and R2 each independently represent a halogen atom, an alkyl group comprising 1 to 6 carbon atoms, or an alkoxy group comprising 1 to 6 carbon atoms,
• X represents a single bond, an alkylidene group comprising 1 to 8 carbon atoms, an alkylidene group comprising 2 to 8 carbon atoms, a cycloalkylene group comprising 5 to 15 carbon atoms, a cycloalkylidene group comprising 5 to 15 carbon atoms, a fluorenediyl group, an arylalkyl group comprising 7 to 15 carbon atoms, an arylalkylidene group comprising 7 to 15 carbon atoms, —S—, —SO—, —SO2—, —O—, or —CO—,
• a and b each independently represent an integer of 0 to 4;
