Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition with excellently balanced rigidity and surface hardness.SOLUTION: The polycarbonate resin composition includes: 100 pts.mass of a polycarbonate resin (A), which includes a polycarbonate resin (A1) having a specific structure unit and viscosity average molecular weight (Mv) of 20,000-35,000 and a polycarbonate resin (A2) having a specific structure unit and viscosity average molecular weight (Mv) of 16,000-30,000 at a mass ratio (A1)/(A2) of 80/20 to 20/80; and 5-100 pts.mass of an inorganic filler (B). The polycarbonate resin composition has pencil hardness of HB or higher when measured according to JIS K5600.
