Abstract
In a sealed structure consisting of ceramic members opposing each other and a frame coupled to the ceramic members and defining an He-tight chamber with the ceramic members, the melting point of a joint member for bonding one of the ceramic members to the frame is lower than the melting point of another joint member for bonding the other of the ceramic members to the frame so that rebonding can be made.
