1. A method of producing a carrier in which catalyst particles or adsorbent particles are carried on a surface of a metal base material made of aluminum or an aluminum alloy, the method comprising:
performing an etching process using an etchant containing iron chloride and nitric acid on the surface of the metal base material made of aluminum or the aluminum alloy, to convert the surface to an uneven and rough surface;
performing an anodizing process on the uneven and rough surface of the metal base material, to form a porous coating along the uneven and rough surface; and
causing the catalyst particles or the adsorbent particles to be carried on the surface of the metal base material on which the porous coating is formed along the uneven and rough surface, wherein
the carrier is a catalyst carrier or an adsorbent carrier.
