In order to reduce bearing loss that originates in an insufficiently lubricated area on a pad facing a thrust collar, a thrust bearing according to at least one embodiment of the present invention is provided with a thrust collar, and at least one bearing pad provided along the circumferential direction on a bearing surface, the bearing pad having a tapered part and a land part. Each of the bearing pads is formed so that a peripheral part on the radially outer side draws near to the radially inner side as the peripheral part progresses upstream in the rotational direction.
