PROBLEM TO BE SOLVED: To provide a clear case capable of easily forming a gore part even a material has high rigidity or melting temperature and difficulty in temperature management in a solvent welding. SOLUTION: In a storing case 1 in which a first sheet 4 and a second sheet 3 are provided so as to oppose to each other, and a right side face part 30, a left side face part 31 and a lower side face part 32 are provided at the end parts of these sheets, ridged parts 30a, 31a and 32a and valley folding parts 30b, 31b and 32b are provided at the end parts of the second sheet 3, the end parts of the second sheet 3 which are extended from the valley folding parts 30b, 31b and 32b are projected from the mountain folding parts 30a, 31a and 32a, and the projection parts 30d, 31d and 32d are weld.
