5. A photocatalytic reaction device, comprising:
an intake port formed in a casing;
a discharge port formed in a side face of the casing different from said intake port;
a centrifugal blower for feeding fluid flowing in from said intake port to said discharge port;
a photocatalyst carrier carrying photocatalyst and being provided in a fluid path between said intake port and said discharge port;
a series of vanes of said centrifugal blower provided facing an opposite side of said photocatalyst carrier to that of said intake port; and
a deodorizing filter provided facing said discharge port,
wherein said discharge port is formed over an entire surface of the side face of said casing, and
wherein said casing is practically rectangular in projection from a direction perpendicular with respect to said intake port,
at least part of a portion of said casing facing said photocatalyst carrier and a periphery thereof is transparent, and
said photocatalyst carrier is provided facing said intake port.
