である。According to the present invention, there is provided an air purifying apparatus having a blower, a photocatalyst member, and a light source for emitting light for exciting the photocatalyst in a housing having an intake port and an exhaust port. The air purifier is disposed at an angle with respect to the flowing direction of the honeycomb-shaped photocatalyst member. The honeycomb-shaped photocatalyst member arranged at an angle receives the excitation light, and the excitation light leaked from the honeycomb-shaped photocatalyst member is emitted from the light source because the photocatalyst member arranged on the inner surface of the housing receives the excitation light. Light is almost completely utilized for the photocatalytic reaction, which can significantly increase the efficiency of the air purifying effect.
