PROBLEM TO BE SOLVED: To reduce residual gas quantity by enabling disposal without separating absorbent, and charge of the absorbent by machine. SOLUTION: In a liquefied gas cylinder 1, the absorbent 4 is charged to a cylinder main body 2, and an inner end of a jet nozzle 5 is inserted into a cavity part 3 at a center. Thick and light paper sheet material is used for the absorbent 4 for sufficiently containing liquefied gas to be vaporized at the cavity part 3. When roll paper is used for the absorbent 4, its form is fixed, so that it can be charged by machine. In addition, by use of 100% pulp paper, a used gas cylinder can be disposed of without separating the absorbent. Since a gas phase exists on both surfaces of the sheet material, contact area for vaporization is increased.
