<P>PROBLEM TO BE SOLVED: To provide a bag body including gas where, to a body part formed with a plurality of hollow parts, valve element parts communicating with the respective hollow parts are mounted, and a method of manufacturing the same. <P>SOLUTION: A plurality of hollow parts 10A each having an elongated shape are formed in a body part 10 mainly formed of a resin sheet by being connected to one another, and the respective hollow parts 10A include openings 10D opening in the same direction. An injection part 20 is formed of a resin sheet, wherein a ventilation path 20A continuing in the X-direction and a plurality of valve element parts 20B projecting in the Y2-direction from the ventilation path 20A are integrally formed. The respective valve element parts 20B are inserted into the hollow parts 10A from the openings 10D, and the body part 10 and the injection part 20 are heat-sealed together. As a result, the valve element parts 20B can be individually connected to the respective hollow parts 10A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
