摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a transparent thermoplastic resin pellet including few foreign matters and less tinged with yellow.SOLUTION: A method for manufacturing a transparent thermoplastic resin pellet includes a step of mixing transparent thermoplastic resin using a kneader under the condition that the damage history calculated by the following formulae is 500-2500. Damage history=residence time (tr)×shear rate (γ). Residence time (tr)=(W×H×L)/Q. Shear rate (γ) = (π×D×N)/H. [In the formulae, W represents a screw groove width (pitch) [cm], H represents a screw groove depth [cm], L represents a screw length [cm], Q represents a resin supply amount [g/s], D represents a screw diameter [cm], and N represents a screw speed [rps]].
