<P>PROBLEM TO BE SOLVED: To solve the following problem that, when a magnetic resin material is injected from a gate located at one end in the longitudinal direction of a cavity formed by combining a movable mold and a fixed mold, at the gate side, a PL surface where the fixed mold and the movable mold are combined is liable to be abraded. Ž<P>SOLUTION: At the gate sides of cavity surfaces of the movable mold and the fixed mold, gate side insert acceptance holes are formed, respectively. A gate side insert is inserted into each of the gate side insert acceptance holes of the movable mold and the fixed mold and fixed, so that the cross-sectional area at the gate side of a lengthy molding is decreased while keeping the similarity of the configuration.
