摘要： Disclosed are composite pellets for extrusion molding wherein fusion does not occur between the pellets, and there is no variation in size and density. A molten material obtained by an extruder for a raw material containing a thermoplastic resin and wood powder is extruded into a strand shape through a die nozzle of the extruder, and cut into a predetermined length to form a pellet. At this time, the extrusion amount, the diameter of each nozzle hole, and the number of nozzle holes are adjusted so that the linear velocity (Åd) of the molten material in each nozzle hole of the die nozzle is in the range of 12 to 50 cm/sec. Further, regardless of the variations in particle diameter, etc., a stable amount of the composite pellets are supplied to the extruder, and smoothly introduced to a screw of the extruder. The composite pellets and 12-hydroxystearic acid containing a metal of Ca, Mg, or Zn are agitated together, and 0.03 to 0.4 mass% of the 12-hydroxystearic acid is attached to the periphery of 100 mass% of the composite pellet, and the pellets are used for extrusion molding.
