PURPOSE:To reduce a manufacturing cost of a mold to be used for molding of a sheetlike member. CONSTITUTION:A bending line 12 is established beforehand on one side 14 of a sheetlike member 10 and a mold 22 having a linear or beltlike form corresponding to the bending line 12 on viewing plainly the side 14 is prepared. A bending line 12 part of the sheetlike member 10 is heated through the mold 22. Since the sheetlike member 10 is deformed so as to bend backward naturally at the bending line 12 part through this heating, the sheetlike member 10 can be molded. The sheetlike member 10 can be molded by making use of the mold 22 having a simple form. |
