The effect of Pb in Ag on the diffusion bonding of Al_2O_3 and Ag has been investigated. The Ag-Pb alloys were Pure Ag, Ag-0.5mass%Pb, Ag-1. OPb and Ag-2. OPb. Al_2O_3 was A-473 produced with KYOCERA Co. Ltd. The welding was carried out at 1073K for 3.6ks, 7.2ks and 14.4ks under the pressure of 2MPa and 4MPa in the atmosphere. Bonding strength was examined with the tensile shear fracture test. Distribution of each element near bonding interface and on shear fracture surfaces of couples is investigated with EPMA. The good results could not be obtained in the couples of Ag-1. OPb/Al_2O_3 and Ag-2.0Pb/Al_2O_3, but be obtained in the couples of Pure Ag/Al_2O_3 and Ag-0.5Pb/Al_2O_3. The bonding strength was increase with time, but it was not almost affected by pressure.
