PROBLEM TO BE SOLVED: To solve conventional problems that in a compression bag formed with a contents inlet part and a deaerating part respectively on a part of the bag, parts of contents are sucked by an air flow and caught in the deaerating part depending on a manner that the air flows during deaeration, and that in a compression bag with a viscous substance applied on a passage of the deaerating part, the contents possibly come into contact with the viscous substance and get contaminated depending on a position of the contents due to the similar reason to the above. SOLUTION: By providing a spot seal 6 on a position at a side end inside the compression bag of a deaerating passage 5, contents such as clothes inside the compression bag 1 can be prevented from being caught inside the passage 5 during deaeration. In addition, since an auxiliary deaerating passage 7 is provided on a separation 4, air existing in a space 23 inside the bag of the contents inlet part 21 can be quickly deaerated. Thus, deaeration can be smoothly performed. Since, in addition, non-return seals 8, 8 and 8 or a liquid seal 9 are provided in the deaerating passage 5, air can be prevented from returning to the inside of the compression bag 1.
