To provide a slide bearing with a low-cost and simple structure, configured to maintain low friction torque without requiring a heat insulating sleeve, while preventing an increase in friction coefficient or wear to be caused when a slide member is stuck to an inner ring.

The slide bearing 1 includes an inner ring 2, an outer ring 3 and a slide member 4 comprising a molded body of a resin composition interposed between the inner ring 2 and the outer ring 3. The inner ring 2 has a curved surface formed on its outer circumference, and a bearing hole 5 formed on its inner circumference and fitted to a support shaft. The slide member 4 is a ring-shaped body having one engagement part 4a, and has a curved surface formed in its inner circumference and coming in contact with the curved surface on the outer circumference of the inner ring 2. The outer ring 3 holds the slide member 4 on its inner circumference side. A protrusion 3a formed on the inner circumferential surface of the outer ring 3 is fitted to the engagement part 4a of the slide member 4.
