Claim:
A manufacturing method of a hermetically sealed container, comprising steps of: placing a first bonding material and a second bonding material on one of surfaces disposed in opposition to each other of first and second members forming the hermetically sealed container, wherein a compressibility of the second bonding material is larger than a compressibility of the first bonding material in relation to a pressing force, and the second bonding material is placed in an annular loop on the one of the surfaces disposed in opposition to each other of the first and second members, the first bonding material is arranged at an outside of the second bonding material placed in the annular loop, in abutting to the second bonding material, and the first bonding material has a height lower than a height of the second bonding material; pressing the first and second bonding materials by the other of the surfaces disposed in opposition to each other of the first and second members, such that both of the first and second bonding materials contact the other of the surfaces disposed in opposition to each other of the first and second members; heating the first bonding material contacting the other of the surfaces disposed in opposition to each other of the first and second members.
