Disclosed is a multi-layered plain bearing which comprises a steel back, an intermediate layer made of an aluminum alloy and an aluminum-base bearing alloy layer comprising one or more elements selected from the group consisting of Cu, Zn, Mg and Si. The aluminum-base bearing alloy layer is bonded to the steel back via the intermediate layer and subsequently subjected to a solid solution treatment at a temperature of not lower than 400null C. The adjacent region of the intermediate layer to the steel back consists of, by mass, 2% to 8% of Si, and the balance of Al and incidental impurities.
