Abstract: An air purifier according to an aspect of the present disclosure includes: an air passage defined between a first inner wall surface and a second inner wall surface that are planar and face each other, having a flat passage cross section in which a distance between the first inner wall surface and the second inner wall surface is small, and meandering in a plane parallel to the first inner wall surface and the second inner wall surface; a catalyst member including a support having a flat mesh shape, and a photocatalyst supported on the support, the catalyst member being disposed parallel to the first inner wall surface and the second inner wall surface in the air passage; and a plurality of light sources dispersed on the second inner wall surface, and configured to irradiate the catalyst member with light that activates the photocatalyst.
