Abstract
A molded article having a photocatalytic function, a desired shape, a large contact area, and being sufficiently irradiated with ultraviolet rays, even at an inner surface thereof. Unit particles such as glass beads, or filaments such as fibers, are bonded to one another into the desired shape. Subsequently, a photocatalytic functional layer is formed on a surface of each particle or fiber. Particles of a spontaneous emission ultraviolet radiating material or light storage-type ultraviolet radiating material may be mixed in the molded article.
