To be able to reduce (i) the equipment cost as compared to non-uniform thickness formed by flow-forming, (ⅱ) to be able to enhance the productivity, (ⅲ) to achieve one or more of the will to improve the appearance quality which provides a method for producing the tubular member. Method of manufacturing a tubular member according to the present invention comprises (a) cylindrical in the axial direction one end process and, with the side (b) a punch (26) bent to form the bent part 8 of the shaped material 4, the uneven surface ( with walking to 24) to the die 22 and the pressing die 22 by a member 23 which ironing device 20 tubular material (4) using the provided with a bent part 8, and then, hyeopap the bent part 8 to the pressing member 23 and the die 22, then, a child the portions other than the bent part 8 of the tubular material (4) to the punch 26 and the die 22 earnings processed by a step of manufacturing a tubular member (10) of non-uniform thickness.
