A stabilizer bushing has a holding hole for holding a stabilizer bar and is to be mounted on a mounting surface of a vehicle-body-side component. A normal line to the mounting surface extends in a direction intersecting an up and down direction of a vehicle. The stabilizer bushing has at least one separation surface, one end portion of which is located on an inner circumferential surface opposed to the holding hole, and the other end portion of which is located on an outer surface of the stabilizer bushing at a position different from a rigid-component opposed portion opposed to the vehicle-body-side component. The at least one separation surface has a first separation surface located nearer to the rigid-component opposed portion than a plane extending through a central axis of the holding hole and parallel with the rigid-component opposed portion.
