Abstract
A bonding composition comprising a metal oxide melt comprising (a) CaO, (b) SiO.sub.2 and/or Al.sub.2 O.sub.3, and (c) a metal oxide selected from TiO.sub.2, ZrO.sub.2, Cr.sub.2 O.sub.3, HfO.sub.2, Nb.sub.2 O.sub.3 and Ta.sub.2 O.sub.5 is melt-bonded on the surface of a ceramic material, and the ceramic material is bonded to an adherend, if necessary through at least one layer selected from a plating layer, a solder layer, and a buffer layer. In this manner, a strong bonding can be very easily obtained.
