Provided are a hollow drive shaft and a method for manufacturing the same in which a concentrated load to a weak point which may be occurred by differences of sectional thicknesses and outer diameters of the shaft is dispersed so that the strength may be uniform throughout the whole length of the drive shaft. The hollow drive shaft includes: one or more small-diameter portion having a hollow shape; and a large-diameter portion which is disposed in a vicinity of the small-diameter portion and has an outer diameter relatively greater than the small-diameter portion. A sectional thickness of the large-diameter portion is less than a sectional thickness of the small-diameter portion, and a first sectional portion from an outer surface to a point corresponding to 35% to 60% of a sectional thickness of the large-diameter portion is carburized to have a first hardness.
