본 발명은, 폴리카보네이트계 수지(A)와, 하기 식(1)로 표시되는 퍼플루오로알킬설폰이미드(B)를 포함하고, (분기제 유래의 구조 단위의 몰수)/(2가 페놀 유래의 구조 단위의 몰수+분기제 유래의 구조 단위의 몰수+말단 단위의 몰수)×100에 의해 산출되는, 상기 폴리카보네이트계 수지(A)의 분기율이 0.30몰% 이상 3.0몰% 이하이며, 상기 퍼플루오로알킬설폰이미드(B)의 함유량이, 상기 폴리카보네이트계 수지(A) 100질량부에 대해서, 0.05질량부 이상 2.0질량부 이하인, 폴리카보네이트계 수지 조성물에 관한 것이다. TIFFpct00023.tif2369 The present invention relates to a polycarbonate-based resin composition including: a polycarbonate-based resin (A); and a perfluoroalkylsulfonimide (B) represented by the following formula (1), wherein the polycarbonate-based resin (A) has a branching ratio of 0.30 mol% or more and 3.0 mol% or less, which is calculated from the expression "(number of moles of structural unit derived from branching agent)/(number of moles of structural unit derived from dihydric phenol+number of moles of structural unit derived from branching agent+number of moles of terminal unit)×100," and wherein a content of the perfluoroalkylsulfonimide (B) is 0.05 part by mass or more and 2.0 parts by mass or less with respect to 100 parts by mass of the polycarbonate-based resin (A).
