PROBLEM TO BE SOLVED: To make a gate trace in a blow molded product less prominent without working the gate trace of a parison after injection molding. SOLUTION: A bottomed parison 1 is injection molded in order that a gate trace 1a is formed on the inner surface of a bottom part. In biaxial stretch blow molding using the parison 1, a drawing rod 7 is made to contact the gate trace 1a formed on the inner surface of the bottom part of the parison 1, and the parison 1 is oriented longitudinally by the rod 7 and oriented laterally by blowing.
