摘要： In an extrusion die in which a mandrel ring is outwardly arranged around a spindle, the present invention aims to enhance the fixing stability of the mandrel ring and enables easy maintenance. The extrusion die includes a mandrel (30) for forming an inner surface of an extruded material. The mandrel includes a spindle (32) and a mandrel ring (35) outwardly arranged around the spindle (32). The mandrel ring (35) is made of a material having a coefficient of thermal expansion smaller than that of a material of the spindle (32). In a state in which the mandrel ring (35) is outwardly arranged around the spindle (32), the extrusion die is configured such that a gap is formed between an outer circumferential surface (32a) of the spindle (32) and an inner circumferential surface (35a) of the mandrel ring (35) at a normal temperature and the gap disappears at least partially in an axial direction of the mandrel (30) to allow contact of both the outer circumferential surface of the spindle (32) and the inner circumferential surface of the mandrel ring (35) at a die temperature at the time of extrusion.
