Abstract:
1. A manufacturing method of an envelope for an image display apparatus comprising: providing a pair of base members, one of the pair of base member has a different value in a heat capacity and a CTE from the other of the pair of base member; arranging a plurality of bonding materials between the pair of base members on top of one another such that one of the plurality of bonding materials faces said one of the pair of base members which has a larger heat capacity than said the other of the pair of base members and the other of the plurality of bonding materials faces said the other of the pair of base members; and bonding the pair of base member by irradiating an electromagnetic wave to the plurality of bonding materials, wherein said one of the plurality of bonding materials has a larger CTE than said the other of the plurality of bonding materials and a difference of a CTE between said one of the plurality of bonding materials and said the other of the plurality of bonding materials is within 10×10 wherein the CTE indicates a coefficient of thermal expansion.
