PROBLEM TO BE SOLVED: To provide a polymer bag-like body which is excellent in resistance to pressure and in durability, is flexible and good in touch, and a method for manufacturing it. SOLUTION: The polymer bag-like body comprises a pillar connected to internal walls facing inside provided in a main body 3 of the bag-like body formed in the form of a bag, while the bag body is covered by a bag-shaped cloth 4. The pillar has a hollow, and the main body and the bag-shaped cloth are integrated by a fixing thread 42 passing through the hollow. Therefore, due to a structure comprising the bag-shaped cloth having a form corresponding covered on the main body and the cloth fixed by passing the fixing thread through the hollow of the pillar, first, resistance to pressure is defined by strength and density of a connecting thread thereby easily improving the resistance to pressure. Since the pillar is not provided by gluing, it may not peel if exposed to a liquid, resulting in improvement in durability. In addition, since the main body and the bag-shaped cloth are not coupled, flexibility may be improved.
