Zusammenfassung:	Disclosed herein is a forming disk (10) for fabricating a formed fin (4) of a fin tube (3). The forming disk (10) is formed of a circular plate having a shaft connection hole (13) penetratingly formed at the center thereof for being connected to a shaft of a form rolling machine. A projection (12) having a certain length is formed along the circumference thereof at certain regular angular intervals in such a way as to be protruded in a radial direction, and a round curvature is formed in the formed fin (4) at certain axial pitch periodically in a radial direction. Also disclosed is a high-performance and high-efficiency fin tube (3). The formed fin (4) is formed of a generally circular plate, and a crest (7) and a valley (6) are formed in both side faces at certain angular intervals along the circumference thereof so as to form a continuous curvature.
