A flip-up part 11t which is bent to the swollen side in longitudinally-sectional view along the short-side direction SD is provided at both end portions in the short-side direction SD so as to extend along the longitudinal direction LD. A manufacturing method comprises a bending-processing step of folding both the end portions in the short-side direction SD to one side to form a bending-processed member, and a drawing-processing step of drawing the bending-processed member so that the bending-processed member swells to one side in a dome-shape, thereby forming a drawing-processed member.
