Provided is a slide bearing capable of retaining strength while achieving weight reduction and cost-cutting. The slide bearing has an upper case () to be attached to an upper support for attaching a suspension to a vehicle body, a lower case () rotatably combined with the upper case (), an annular center plate () located between the upper case () and the lower case (), and an annular sliding sheet () located between the upper case () and the center plate (). The lower case () has a lower case body () in a substantial cylindrical shape, a flange part () projecting radially outward from an outer peripheral surface of the lower case body (), and hollow sections () formed on an outer peripheral surface of the flange part (). A plurality of the hollow sections () are formed at equal intervals in a circumferential direction on the outer peripheral surface of the flange part ().
