A disc-shaped baffle member is disposed, and the bridge portion of the baffle member that separates the introduction holes from each other is set in a positional relationship such that it crosses the molding material introduction hole of the male mold. When continuously extruding these billets, the molding material of these billets repeats branching and merging while passing through the baffle member, the male mold, and the female mold, and meanderes significantly, so that the joint surface of the molding material of the front and rear billets is greatly deformed over its entire surface. Therefore, the strength of the joint portion of the molding material in the extruded material is improved, and the extruded material can be made to have excellent strength over its entire length. Furthermore, unlike in the past, cutting and removing portions with poor bonding strength is not necessary, so the yield of molding material can be improved and economical efficiency can be improved.
