To provide an extruding die for a hollow shape material by which an extruding speed can be increased while suppressing an extruding load without the occurrence of cracks to the cross section and the occurrence of shrinkages to the cross-sectional thickness part.

The extruding die 11 for the hollow shape material is provided with a mandrel 13 for molding the internal shape of the hollow shape material, a male die 12 having a bridge 14 for supporting the mandrel 13, and a female die 15 having a hole 16 for molding the external shape of the hollow shape material. A flow face 14b, with which a molding material during flowing comes into contact when the extrusion molding is executed, is formed to the bridge 14. A dead metal part D, which is located between the rear end 14a in the extrusion direction of the bridge 14 and the mandrel 13 and recessed inwardly in the die diameter direction, is provided to the flow face 14b.
