Disclosed are a method of manufacturing composite pellets comprising: when the pellets are formed by extruding a molten material obtained by melt-kneading a raw material containing thermoplastic resin and wood meal with an extruder into a strand through nozzle holes in a nozzle mounted at a front end of the extruder, then cutting the strands to a predetermined length, to set the rate of extrusion (Q) of the extruder, the diameter (D) of each of the nozzle holes, and the number (n) of the nozzle holes such that a linear velocity (vd) falls within a range of 12 to 50 cm/sec, wherein vd = (Q 1000/3600)/[(D/20)2.pi. .cndot. .rho.m .cndot. n], where vd = linear velocity (cm/sec), Q = rate of extrusion by the extruder (kg/Hr), D = diameter of each nozzle hole (mm), n = number of nozzle holes, and .rho.m = density of molten resin (g/cm3). |
