(57) [Problem] An object of the present invention is to provide a photocatalyst member having heat exchangeability, preferably total heat exchangeability, and excellent air cleanliness. A partition plate (1) having heat conductivity, preferably moisture permeability, is superposed on a plurality of layers at predetermined intervals, and a primary air flow (3) and a secondary air flow (4) alternate between these layers. The photocatalyst member which carries a photocatalyst at the end part (5) of the ventilation surface of the air-permeable member formed so that it may pass. |
