PROBLEM TO BE SOLVED: To provide a substrate case that is prevented from being opened without destroying both of a sealed seal and a protective cover member to break this.SOLUTION: A case sealing part 100 makes a body side sealing part 110 closely oppose to a lid side sealing part 140 by relatively moving a case lid member in the case closing direction to a case body member in order to bring a main substrate case into a closing state. Then, a protective cover member 130 temporarily secured to the body side sealing part 110 is engaged and connected with the lid side sealing part 140, and opens the main substrate case from the closing state. Accordingly, when the case lid member is relatively moved to the case body member in the case opening direction and the body side sealing part 110 is separated from the lid side sealing part 140, the protective cover member 130 comes into abutment with a sealed seal and breaks this while maintaining an engagement state with the lid side sealing part 140, and also the protective cover member 130 itself comes into contact with the lid side sealing part 110 and is destroyed. |
