Disclosed is a surface-treated metal material comprising a composite coating film which is obtained by applying an aqueous metal surface treatment agent over the surface of a metal material and drying the agent thereon. The aqueous metal surface treatment agent is composed of an organosilicon compound (W) obtained by blending a silane coupling agent (A) having one amino group in a molecule and a silane coupling agent (B) having one glycidyl group in a molecule at a solid content mass ratio [(A)/(B)] of 0.7-1.7, at least one fluorocompound (X) selected from titanium hydrofluoric acid and zirconium hydrofluoric acid, phosphoric acid (Y), a vanadium compound (Z) and a lubricating agent (J). L'invention concerne un matériau métallique traité en surface comprenant un film de revêtement composite obtenu par application d'un agent de traitement de surface métallique aqueux sur la surface d'un matériau métallique et par séchage de l'agent sur celle-ci. L'agent de traitement de surface métallique aqueux inclut un composé organo-silicium (W) obtenu par mélange d'un agent de couplage de silane (A) dont une molécule inclut un groupe aminé et d'un agent de couplage de silane (B) dont une molécule inclut un groupe glycidylique à un rapport massique de teneur en matières solides [A/B] de 0,7-1.7 , au moins un fluorocomposé (X) choisi parmi l'acide fluorhydrique de titane et l'acide fluorhydrique de zirconium, l'acide phosphorique (Y), un composé de vanadium (Z) et un agent lubrifiant (J).
