PROBLEM TO BE SOLVED: To prevent occurrence of cracks caused by difference in thermal expansion and to improve brazing properties, by supporting granules on gold. SOLUTION: A metal or a nonmetal granule having >=50 deg.C melting point and 0.1-100μm particle diameter in an amount of 0.01-8.0vol.% is supported on gold or a gold alloy to give a complex gold material for brazing a metal to a ceramic, having >=4.0×10<-6> />= (20-500 deg.C) difference in coefficient of thermal expansion. The surface of a ceramic to be bonded is coated with a coated film of Ti having 0.1-1.0μm thickness, which is coated with a coated film of Ni having 0.5-5μm thickness. The complex gold material for brazing is bonded to the coated ceramic to carry out brazing.
