PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition excellent in mechanical strength, electric characteristics and transparency, and exhibiting little yellowing caused by convection current in a molding machine. SOLUTION: This electrostatic polycarbonate resin composition is prepared by dispersing a sulfonic aid phosphonium salt, carboxylic acid ester solution dissolving lithium bis(trifluoromethanesulfonyl)imide or sulfur-containing ester compound solution. The sulfonic acid phosphonium salt and the lithium salt compound are uniformly dispersed like being dissolved, since the solution obtained by dissolving the lithium salt with the carboxylic acid ester or sulfur-containing ester compound is prepared in advance and the solution is kneaded into the polycarbonate resin composition together with the sulfonic acid phosphonium salt.
