PROBLEM TO BE SOLVED: To provide a method for making the surface of a metal such as aluminum and titanium or an alloy material thereof electroconductive. SOLUTION: A surface treatment method comprises the steps of: dispersing indium-oxide-based, antimony-oxide-based or zinc-oxide-based electroconductive fine particles in water or an other solvent; making the dispersion into mist by applying an ultrasonic wave thereto; introducing the mist into a high-temperature furnace of 200°C or higher; heating the fine particles to 150 to 600°C; contacting the high-temperature fine particles with the alloy material of aluminum or titanium, of which the surface is made non-electroconductive, for 0.5 second or longer; and at the same time, applying a voltage of 1 to 100 KV between the fine particles and the surface of the alloy to form an electroconductive coating on the material surface.
