PROBLEM TO BE SOLVED: To provide a method of manufacturing a heat conducting body which can secure a sufficiently large heat conducting surface area by reducing the overhung amounts of bent fins and increasing the number of formed fins per prescribed length of the heat conduction body and, at the same time, can be reduced in ventilation resistance to ventilated air and does not cause fluctuation in the quality, such as the thicknesses, heights, etc., of the formed fins. SOLUTION: The fins 3 are formed by skiving the heat conducting body 20 by means of a cutting tool 20 having an included angleαof 40-55 deg. in a state where the cutting incident angleθof the tool 20 to the surface of the body 2 is set at 4.5-9.5 deg..
