A functional material has a metal substrate and exhibits at least one of the following: an antimold action, an antimicrobial action, and an antiviral action. The functional material is provided with: a metal substrate produced by forming a zinc layer on the surface of an aluminum substrate; and a functional film that is a zinc phosphate film formed on the surface of the metal substrate. A micron-order unevenness is formed on the surface of the functional film, as a result of which the functional film has at least one of the following: an antimold action that prevents the proliferation of mold, an antimicrobial action that kills microorganisms, and an antiviral action that inactivates viruses. The functional material is produced by carrying out a zinc phosphate chemical conversion treatment on the surface of an aluminum substrate and forming on this surface a zinc phosphate film having micron-order unevenness.
