Abstract | [Problem] To provide a metal material itself and a method for producing the same, the metal material having a passive film on the surface thereof to be corrosion-resistant and also having low contactresistance, wherein the metal material includes a metal material preferable for a separator or a current collector plate which is for a fuel cell. [Solution] Conductive particles 3 are embedded in andattached to a metal substrate 1 having a passive film 2 on the surface thereof such that the conductive particles 3 penetrate the passive film 2 in the thickness direction, wherein the surface of themetal substrate is covered with a coating film having conductivity and corrosion resistance. To attach the conductive particles in such a way, the conductive particles 3 are scattered on a certain metal substrate 1, and the passive film 2 is pressed down with a roll, etc., whereby the conductive particles 3 are pushed into the surface of the metal substrate 1.
