Abstract
To provide an aluminum alloy member having a high machinability while keeping a sufficient mechanical strength and a sufficient wear resistance, and a method of producing the aluminum alloy member. In an aluminum alloy member formed from an aluminum-silicon alloy by casting, eutectic silicon grains are exposed from at least part of an exposed plane of the aluminum alloy member. A coating layer having a thickness nearly equal to or thinner than a diameter of each of the eutectic silicon grains is formed on the exposed plane from which the eutectic silicon grains are exposed.
