PROBLEM TO BE SOLVED: To provide a storage case, the strength of which can be improved, even composing it with a cover body having a uniformly flat surface, and the capacity of which can be readily confirmed from its appearance, and a die for molding the same. SOLUTION: This storage case 1 having a case body 2 and a cover body 3 for covering the top surface of the case body 2, is provided with inclined surfaces 4a to 4d inclined gradually upwardly from a frame portion 3a surrounding the cover body 3 toward the center part, and is formed with ridges 5a to 5d on borders between the respective inclined surfaces. A planar portion 3b, in which the inclined surfaces 4a to 4d are formed, is integrally formed with the frame portion 3a toward the inside of the case body 2 in concavity shape, and provided at equal position in height to the top edge portion 2a of the case body 2. |
