An aluminum alloy bearing for use in a low-rigidity housing, includes a bearing aluminum alloy, and a steel back metal bonded to the bearing aluminum alloy. The steel back metal contains 0.16 to 0.35 wt. % of carbon, and the steel back metal has a hardness of Hv 200 to 280 and has an elastic limit of not less than 40 kgf/mm2. For producing the aluminum alloy bearing, the back metal material is pressure-bonded to the bearing aluminum alloy in such a manner that the rolling reduction of the back metal material is 38 to 50%.
