Abstract

A metal hollow member (1) having a plurality of hollow portions (10) extending in a longitudinal direction thereof and communication apertures (12) formed in a partitioning wall (11) partitioning adjacent hollow portions is formed by: extruding a molten extrusion material through a die comprising a female die (3) for forming an outer peripheral portion of the metal hollow member and a male die (2) including a plurality of hollow-portion-forming protrusions (2a) corresponding to the plurality of hollow portions (10); and intermittently supplying fluid insoluble in the molten extrusion material into the partitioning wall from a bottom portion of a groove formed between the adjacent hollow-portion-forming protrusions (2a) while extruding the molten extrusion material, whereby the plurality of communication apertures (12) are formed by fluid-released-apertures (6) from which the fluid is released.
