To enable a container for hermetically sealing a workpiece to be downsized and a highly accurate leakage test to be performed, even when the workpiece has an extending portion.SOLUTION: A hermetic container 1 is used for performing a leakage test on a workpiece 100 having cross-sectionally circular extending portions 101, 102. The hermetic container 1 comprises container half bodies 10, 20, with a leakage test object part 105 of the workpiece 100 hermetically sealed by the joined state of these. Penetrations 6, 7 for putting the extending parts 101, 102 therethrough while in the joined state are formed in the first container half body 10 by notches 12, 13 and the notches 22, 23 of the second container half body 20. The interval between the joined surfaces of the container half bodies 10, 20 is sealed by a main seal part. A sub-seal part 40 is provided in each of the notches 12, 22, and the other seal part 50 is provided in the notches 13, 23. The sub-seal parts 40, 50 respectively have a semi-circular arc sealing surfaces 41, 51. The hardness of the sub-seal parts 40, 50 is lower than the hardness of the main seal part.SELECTED DRAWING: Figure 1 【課題】ワークが延出部を有していても、ワークを密封する容器を小型化でき、高精度のリークテストを行なえるようにする。【解決手段】密封容器１は、断面円形の延出部１０１，１０２を有するワーク１００をリークテストするために用いられる。密封容器１は容器半体１０，２０を備え、その接合状態で、ワーク１００のリークテスト対象部１０５を密封する。第１容器半体１０には切欠部１２，１３と第２容器半体２０の切欠部２２，２３により、上記接合状態で延出部１０１，１０２を通すための貫通部６，７が形成される。容器本体１０，２０の接合面間は主シール部によりシールされる。切欠部１２，２２にはそれぞれ副シール部４０が設けられ、切欠部１３，２３には他の副シール部５０が設けられている。副シール部４０，５０は、半円弧シール面４１，５１をそれぞれ有している。副シール部４０，５０の硬度は主シール部の硬度より低い。【選択図】図１
