PROBLEM TO BE SOLVED: To provide a joined substrate which is enhanced in bonding strength and has high heat cycle resistance in the final by directly joining molten aluminum to a ceramic substrate having surface roughness of a specific range. SOLUTION: The Al-ceramic compound substrate is constituted by directly joining aluminum melt to the ceramic substrate having the prescribed surface roughness. COPYRIGHT: (C)2006,JPO&NCIPI
