Zusammenfassung:	Provided is a method for manufacturing a magnetic wedge by which productivity can be increased. The manufacturing method comprises: a resin molding step in which a plurality of cavities formed in an upper mold and/or a lower mold that are opposite each other and gaps narrower than the depth of adjacent portions of the cavities and formed between the plurality of cavities and between the upper mold and the lower mold are filled with a resin material containing a magnetic powder, and in that state, the resin material is resin molded through compression molding such that a plurality of products are collectively molded; and a resin layer removal step in which a resin layer formed by the resin molds at the gaps is removed.
