Manufacturing method of image display apparatus, and bonding method of base materials

A manufacturing method of an image display apparatus which comprises a first substrate having numerous electron-emitting devices, a second substrate positioned opposite to the first substrate and having a fluorescent film of displaying an image in response to irradiation of electrons emitted from the electron-emitting devices, and a frame member positioned between the first substrate and the second substrate to form a space between the first substrate and the second substrate, the method comprising:

• arranging a bonding material between a pair of base materials acting as the first substrate and the frame member or acting as the second substrate and the frame member, the bonding material extending along one of the base materials acting as the frame member;
• and
• bonding, as mutually pressing to each other the base materials of the pair of the base materials, the pair of the base materials by the bonding material, by irradiating an electromagnetic wave to the bonding material while moving an irradiation position along the bonding material to melt the bonding material, and then hardening the melted bonding material,
• wherein the arranging of the bonding material includes arranging the bonding material on one of faces of the pair of the base materials mutually opposite to each other so as to have a convex portion which continuously extends in a direction along which the bonding material extends and in which its central region in a width direction protrudes toward the other of the faces of the pair of the base materials.
