Abstract

Provided is a thrust bearing with which a rotating shaft and a sliding surface are not easily damaged by an electric discharge. A thrust bearing (10) receives force acting in an axial direction (X) of a rotating shaft (6) of a vehicle driving motor. The thrust bearing (10) includes: a metal base (20) having an annular shape and an insulating layer (30). The metal base (20) includes a first axial-directional end surface (21), a second axial-directional end surface (22), and two radial-directional end surfaces (23). The insulating layer (30) covers at least the first axial-directional end surface (21) and the two radial-directional end surfaces (23) of the metal base (20). The metal base (20) is constituted by a back metal layer (25) and a bearing alloy layer (26) positioned closer to the first axial-directional end surface (21) than the back metal layer (25) is. A maximum thickness of the insulating layer (30) covering the radial-directional end surfaces (23) of the metal base (20) is larger than 0% and is equal to or smaller than 50% of a minimum thickness of the insulating layer (30) covering the first axial-directional end surface (21) of the metal base (20).
