A functional sheet which exercises desired actions such as healing effect in high efficiency, without restriction by its use condition and the like is provided. A functional sheet 1 which exercises functions such as healing effect, relaxation effect, decomposition and removal of harmful substances according to complex functions such as generation of minus ions and/or photocatalyst function, by supporting a photocatalyst powder 10 such as titania (TiO 2 ), tin oxide (SnO), zinc oxide (ZnO), SnO 2 , ZrO 2 , and WO 3 which is oxidized in a structure of which a bond with oxygen is decreased as goes from its surface into the inside gradually, and a radioactive powder 20 containing a natural radioactive substance such as thorium (Th), for example, the powder of monazite, in a condition in which they are mutually brought in contact or adjacent, on a carrier 30 which forms a sheet shape composed by entangling a lot of fibers such as nonwoven fabric. |
