A method of manufacturing a spherical bearing having an inside member with a metal ball part and an outside member having a ball support part supporting the ball part of the inside member and connected to the inside member swingably or rotatably relative to each other, comprising the steps of performing an injection molding in which the ball part of the inside member is inserted as a core in a die to form a resin liner covering the ball part, molding the outside member covering the resin liner by a casting in which th e ball part and the resin liner are inserted as cores in the die, and after th e completion of the casting, heating the resin liner covering the ball part through the ball part of the inside member.
