NOVELTY - A polycarbonate-type resin composition comprises (in parts mass) alkali metal salt and/or alkaline-earth metal salt of organic sulfonic acid (B) (0.01-0.15), polytetrafluoroethylene (C) (0.1-1) having fibril-forming ability, titanium dioxide particles (D) (2-15), and resin mixture (A) (100) comprising polycarbonate-polyorganosiloxane (PC-POS) copolymer (A-1) (30-100 %mass) having ester-type structural unit (I) and silicon-containing structural unit (II), and aromatic polycarbonate resin (A-2) (0-70 %mass) other than PC-POS copolymer (A-1).    USE - Polycarbonate-type resin composition is used for molded product for structural component for photovoltaic power generation (all claimed) e.g. junction box used in outdoor.    ADVANTAGE - The molded product formed using polycarbonate-type resin composition has excellent flame retardant property, and tracking resistance without deteriorating low-temperature impact characteristics of polycarbonate-polyorganosiloxane copolymer.    DETAILED DESCRIPTION - A polycarbonate-type resin composition comprises (in parts mass) alkali metal salt and/or alkaline-earth metal salt of organic sulfonic acid (B) (0.01-0.15), polytetrafluoroethylene (C) (0.1-1) having fibril-forming ability, titanium dioxide particles (D) (2-15) having coating layer containing polyol which does not contain nitrogen atom in particle outermost surface, and resin mixture (A) (100) comprising polycarbonate-polyorganosiloxane (PC-POS) copolymer (A-1) (30-100 %mass) having ester-type structural unit of formula (I) and silicon-containing structural unit of formula: -(Y'-(Si(-R3)(-R4)-O)n-Si(-R5)(-R6)-Y'-C(=O))- (II), and aromatic polycarbonate resin (A-2) (0-70 %mass) other than PC-POS copolymer (A-1). The average repetition number (n) of organosiloxane constituent units in silicon-containing structural unit (II) is 70-500.    R1,R2=1-6C alkyl or 1-6C alkoxy;    X=single bond, 1-8C alkylene, 2-8C alkylidene, 5-15C cycloalkylene, 5-15C cycloalkylidene, -S-, -SO-, -SO2-, -O- or -CO-;    a,b=0-4;    R3-R6=H, halo, 1-6C alkyl, 1-6C alkoxy or 6-12C aryl;    Y'=organic residue containing aliphatic or aromatic;and    n=average repeating number.    An INDEPENDENT CLAIM is included for molded article, which is obtained by molding polycarbonate-type resin composition.
