Abstract: It is an object of the present invention to provide a photocatalyst-carrying mesh sheet which firmly supports anatase type titanium oxide as a photocatalyst to prevent peeling, and increases opportunities for contact with the photocatalyst to significantly improve a purification treatment efficiency provided by the photocatalyst and to suppress manufacturing cost. A photocatalyst-carrying mesh sheet (S1) is disclosed, which includes: a net-form titanium sheet (11) having a periodic pattern; a titanium oxide film (3) formed on a surface of the net-form titanium sheet (11); and an anatase type titanium oxide particle (4) supported on the titanium oxide film (3).

Abstract: Provided is an air purifier that allows efficient contact between air and a photocatalyst. An air purifier according to an aspect of the invention includes: a light source; a catalytic member which includes a mesh like carrier formed in a tubular shape and a photocatalyst supported on a surface of the carrier, and which is provided outside and spaced apart from the light source; a reflecting tube which is provided outside and spaced apart from the catalytic member, and which reflects light emitted from the light source and transmitted through the catalytic member; and a centrifugal blower which includes an impeller rotating substantially coaxially with respect to the reflecting tube and a housing having an intake port connected to one end of the reflecting tube.
