Abstract
A method for forming a photocatalytic apatite includes a target production step (S) for producing a sputtering target that contains photocatalytic apatite, and a sputtering step (S) for forming a photocatalytic apatite film on a substrate by sputtering using the target. A firing step (S) for firing the photocatalytic apatite is conducted before the sputtering step so as to increase the crystallinity of the photocatalytic apatite.
