In order to provide a leaf type foil bearing that is rotatable with high accuracy and adaptable to higher speed rotation, there is provided a foil bearing (10), including: a cylindrical outer member (11); a shaft (6) inserted on an inner periphery of the outer member (11); and leaves (14) arranged at a plurality of positions in a circumferential direction between an inner peripheral surface (11b) of the outer member (11) and an outer peripheral surface (6a) of the shaft (6). A region including a front end (14a) of each of the leaves (14) serves as a top foil (Tf) that has a bearing surface (14c), and a region including a rear end (14b) of each of the leaves (14) serves as a back foil (Bf) that supports, from behind, the top foil of the adjacent leaf. Any one or both of the front end (14a) and the rear end (14b) of each of the leaves (14) are inclined with respect to an axial direction. |
