A sliding bearing ( 1 ) includes an upper casing ( 3 ) which is made of polyacetal resin as a synthetic resin, has an annular surface ( 2 ), and serves as a first bearing body; a second bearing body ( 5 ) which is made of a synthetic resin, is superposed on the upper casing ( 3 ) so as to be rotatable about an axis (O), and has an synthetic resin-made annular surface ( 4 ) opposed to the annular surface ( 2 ); and a synthetic resin-made annular sheet ( 6 ) which is interposed between the annular surfaces ( 2 ) and ( 4 ) and slidably abuts against at least one of the upper casing ( 3 ) and the bearing body ( 5 ).
