PROBLEM TO BE SOLVED: To provide a method for manufacturing a bearing in which a bearing surface is formed to an electrocast part, efficiently and at low cost. SOLUTION: After the electrocast part 4 is inserted to form a holding part 5 by injection molding and from the start of die opening to demolding of a molded article, the electrocast part 4 is separated from a master shaft 7. Therefore, the separation of the electrocast part 4 can be performed during injection molding step, so that the number of manufacturing steps of the bearing 3 can be reduced and thereby to improve manufacturing efficiency and reduce the cost.
