PROBLEM TO BE SOLVED: To provide an annular insert molded article that suppresses contamination of a metal mold and generation of foreign matter without increase in material costs for an adhesive or contamination of a transfer jig, and has a high adhesion strength so that, when the annular insert molded article is attached to a rotating body, the adhesive is not peeled off the insert to remain as foreign matter in the rotating body; and to provide a manufacturing method of the annular insert molded article.SOLUTION: An annular insert molded article 1 is manufactured by injection molding in a state where a thermoset resin adhesive A is applied to a joint surface of an annular insert 2 attachable to a rotating body with an annular plastic 3 and then the annular insert 2 and the annular plastic 3 are placed in a metal mold. The range of the adhesive A applied to the annular insert 2 is a range not going beyond boundaries B1 and B2 with the annular plastic 3 by more than 3 mm, and the range does not include a portion C of the annular insert 2 to be fitted with the rotating body. |
