A method of producing a fine TiC particle-dispersing type Al-Sn based aluminum alloy includes the steps of: preparing either Al mother-alloy or metallic raw materials of the Al alloy and a green compact, in which TiC is dispersed; melting the Al mother-alloy or the metallic raw materials of the Al alloy to form an Al alloy melt; bringing the Al alloy melt and the green compact, in which TiC is dispersed, into contact with one another, thereby dispersing the TiC in the Al-alloy melt; casting the Al alloy melt, in which TiC is dispersed, into an aluminum-alloy ingot, in which TiC is dispersed; and rolling the aluminum-alloy ingot.
