Zusammenfassung:	To provide a deaeration bag which can prevent damage misrecognition.SOLUTION: A deaeration bag 1 comprises a laminated film 10 with a deaeration port 5a disposed on at least one surface thereof. The laminated film 10 is formed by being laminated with a vapor deposition film 14 having a metal vapor deposition film 14b disposed on a base film 14a and an interior film 11 with a thermo-adhesive resin layer 12. The interior film 11 has small holes 6, and a ventilation path 5 composed of a non-formation part of the metal vapor deposition film 14 b is provided on the base film 14a in communication with the small holes 6. The ventilation path 5 reaches an outer edge of the laminated film 10 and forms the deaeration port 5a.SELECTED DRAWING: Figure 2 【課題】破損の誤認を防止できる脱気袋を提供する。【解決手段】脱気口５ａを有した積層フィルム１０を少なくとも片面に配した脱気袋１において、積層フィルム１０がベースフィルム１４ａ上に金属蒸着膜１４ｂを配した蒸着フィルム１４と、熱接着性樹脂層１２を有した内装フィルム１１とを積層して形成され、内装フィルム１１が小孔６を有するとともに、ベースフィルム１４ａ上に金属蒸着膜１４ｂの非形成部から成る通気路５を小孔６に連通して設け、通気路５が積層フィルム１０の外縁に到達して脱気口５ａを形成する。【選択図】図２
