PROBLEM TO BE SOLVED: To provide a thrust bearing capable of stably supplying a lubrication oil to a slide part. ! SOLUTION: An annular thrust bearing 100 is disposed being sandwiched between end surfaces of two members, which rotate relative to each other, and is made of a resin. The thrust bearing 100 is used in a state where a lubrication oil is supplied to the inner peripheral surface side. In the thrust bearing 100, oil supply passages 110, 120 are formed on both surfaces. The oil supply passages 110, 120 includes: annular grooves 111, 121 provided coaxially with a center axis of the annular thrust bearing 100; first grooves 112, 122 which are provided so as to extend from an inner peripheral surface to the annular grooves 111, 121; and second grooves 113, 123 which are provided so as to extend from the annular grooves 111, 121 to an outer peripheral surface. !
