There is provided an aluminum/ceramic bonding substrate having a high reliability to high-temperature heat cycles. An aluminum member of an aluminum alloy having a Vickers hardness of 35 to 45 is bonded to a ceramic substrate having a flexural strength of 500 to 600 MPa in three-point bending. The ceramic substrate is made of high-strength aluminum nitride, silicon nitride, alumina containing zirconia, or high-purity alumina. The aluminum alloy is an aluminum alloy containing silicon and boron, or an aluminum alloy containing copper.
