To provide a new functional member which has a photocatalytic function including a deodorization effect, an antibacterial effect, and an antifouling effect and can materialize a deodorization function etc., even when sufficient light does not exist.

In the functional member having the photocatalytic function and an adsorption/elimination function, a binder for fixing a photocatalytic substance and a porous adsorbent substance to the surface of a substrate is applied on the surface of the substrate, the porous adsorbent substance carrying the photocatalytic substance is sprayed, and the binder is cured, so that the binder, the photocatalytic substance, and the porous adsorbent substance are fixed to the surface of the substrate.
