Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a forming disk which is used to perform form rolling of a heat exchange fin tube by a method for increasing the heat transfer coefficient by changing the shape of a fin and for enhancing the heat transfer coefficient by flexing the surface of a flat form-rolled fin, and a fin tube of high performance and high efficiency using the forming disk. SOLUTION: The forming disk is disk-shaped, and has a shaft connection hole penetrated at the center to be connected to a shaft of a form rolling machine. Projections having a predetermined length in the radial direction at a predetermined angle on the circumference are included on both side faces, and a circular flex is formed on a formed fin radially at the predetermined period with a predetermined pitch in the axial direction.
