The flexible container relating to the present invention comprises a cylindrical member () made from flexible film, a bottom plate member () which is harder than the flexible film, fitted into the inner side of a first end section of the cylindrical member () and fused-bonding airtightly; and a ring member () which is harder than the flexible film, fitted into the inner side of a second end section of said cylindrical member () and fused-bonding airtightly. According to this flexible container (), it is possible greatly to reduce the volume of the container after discharging the highly viscous material from the flexible container, and it is possible to achieve small and inexpensive molds having excellent productivity as molding equipment for forming the bottom plate member () and the ring member (), thereby achieving benefits in that the price of the equipment can be reduced significantly.
