Zusammenfassung:A thrust foil bearing includes a base plate including an insertion hole through which a rotating shaft is inserted and a support surface disposed around the insertion hole on one side of the insertion hole in an axial direction, and a back foil disposed on the support surface, in which the support surface has a plurality of inclined surfaces of which inclination angles inclined toward the other side of the base plate in the axial direction become shallower in order toward an outside of the insertion hole in a radial direction, and the back foil is divided into a plurality of divided regions in the radial direction by a slit, and the plurality of divided regions are supported by the plurality of inclined surfaces.
