PROBLEM TO BE SOLVED: To provide an extrusion molding die capable of stably molding a molded article having a plurality of hollow holes. SOLUTION: The extrusion molding die (A) forms the molded article having the plurality of hollow holes by performing extrusion molding of molding material. Therein, a flow path 1 through which the molding material flows is formed on a die body 2. A plurality of support bars 4, 4... which partition the flow path 1 with prescribed intervals are disposed on the die body 2. A plurality of pin bases 28, 28... are disposed on both sides of the support bars 4 by a staggered arrangement and, thereby, opening parts 6 of a substantially fixed width are formed between the support bars 4, 4 adjacent to each other. Pin bodies 5 project toward the outlet 7 of the flow path 1 from the pin bases 28. COPYRIGHT: (C)2009,JPO&INPIT
