Zusammenfassung:	There are disclosed an expanded tube processing method and expanded tube processing apparatus of a cylindrical tube, for inclining an opening end portion of a work formed of the cylindrical tube of metal with respect to an axis of a work to perform tube expansion, in which in order to simply perform an expanded tube processing, a punch is disposed on an opening end side of the work of the metal cylindrical tube and the punch is inserted from the work opening end to perform the tube expansion on a work end. A punch 18 is inserted from the work opening end at a predetermined angle to a tube axis A of a work 6. During insertion of the punch 18, the punch 18 and/or the work 6 are moved in a direction Y1-Y2 substantially crossing at right angles to an advancing/retreating drive direction Z1-Z2 of the punch 18 to perform the expanded tube processing.
