PROBLEM TO BE SOLVED: To provide an OA equipment component which is composed of an aromatic polycarbonate resin composition comprising a polymer obtained from biomass resources and is excellent in heat resistance, mechanical characteristics, chemical resistance, and hydrolysis resistance. SOLUTION: The OA equipment component is composed of 100 pts.wt. of a resin component consisting of (A) 95-5 wt.% of an aromatic polycarbonate resin (component A) and (B) 5-95 wt.% of a polylactic acid resin (component B), and 0.0001-10 pts.wt. of at least one kind of compound selected from the group consisting of (C) a phosphoric ester metal salt (component C) and (D) a triclinic inorganic nucleating agent (component D). The stereo complex crystal content (X) represented by the following expression (1) is 80% or more: X (%)=ä▵Hb/(▵Ha+▵Hb)}×100 (1) wherein ▵Ha is fusion enthalpy of a crystalline melting point emerging at a temperature lower than 190°C while ▵Hb is fusion enthalpy of the crystalline melting point emerging at a temperature of 190°C or higher and lower than 250°C.
