Claim:
1. A method for producing a light-transmissive pellet, the method comprising kneading and granulating a polycarbonate resin composition at a ratio Q/Ns that is effective to produce a pellet having a light transmittance at a wavelength of 380 nm of 97.8% or more and having a viscosity-average molecular weight (Mv) of from 11,000 to 22,000, wherein: in the ratio Q/Ns, Q represents a resin supply quantity (kg/h) of a kneading machine, and Ns represents a screw revolution number (rpm) of the kneading machine; and the pellet is adapted to function as a resin material for a light-transmissive member.
