An inter-cooler tube manufacturing method which reduces weight of the inter-cooler tube by maintaining the partition walls as thin sheets while integrally forming plural partition walls within an integrated inter-cooler tube by hot rolling, obtains very good productivity by adopting brazing process, and obtains an inter-cooler tube with excellent mechanical properties and radiation characteristics, and the inter-cooler tube manufactured by the same are provided. A manufacturing method of an inter-cooler tube comprises: a sheet forming step(S10) of a clad sheet with sheet thickness for hot rolling; a matrix sheet fabrication step(S11) of passing the clad sheet manufactured by the step(S10) through a forming equipment comprising hot rolling rolls and forming rolls to fabricate a clad matrix sheet in such a manner that the clad matrix sheet has a half cut type projection sectional shape; a first tube forming step(S12) of making a tube from the fabricated clad matrix sheet to fabricate a partition wall-integrated circular tube; a second tube forming step(S13) of sequentially passing the partition wall-integrated circular tube through plural rectangular rolls to fabricate a partition wall-integrated rectangular tube; and a brazing step(S14) of passing the partition wall-integrated rectangular tube through a brazing equipment.
