Abstract: PROBLEM TO BE SOLVED: To make it possible to form a frame delineating a track width with high accuracy by forming this frame after flattening the stepped part of the insulating layer on a conductor coil and forming the resist used for flattening as part of the frame. SOLUTION: The resist 6 of the film thickness enough to flatten the stepping of the conductor coil 3 and the insulating layer on the coil is applied over the entire surface. This resist is exposed and developed via a photomask, by which the resist 6 in the upper part of the stepping is removed. The resist 6 in the lower part of the stepping is then made to reflow and is thereby flattened. The resist 6 for forming the frame 5 is then applied over the entire surface and is exposed and developed via a photomask, by which part of the frame is formed. Further, the frame is irradiated with UV rays, for UV rays, electron beams, etc. An ion milling method is, for example, used for patterning of the resist 6 previously used for flattening.
