Abstract
A production method enables use of ultrasonic forming but does not leave a bonding face in a final product. One cuts into a plate member having a first side face and a second side face from the first side face toward the second side face to form a slit that does not reach the second side face; seals lips of the slit to leave an opening; causes superplastic forming of the plate member by pressurizing the plate member in a mold with gas through the opening; and cuts out a portion including the sealed lips.
