PURPOSE:To prevent the leakage of the electric current at the edge part of the lower part magnetic film and to execute the satisfactory magnetic recording by preventing the forming of the first electric conductor layer at the edge part of the lower part magnetic film, forming the second electric conductor layer through the insulating layer and executing the electrical connection. CONSTITUTION:A lower part magnetic film 8 pattern-formed by a sputtering method, etc., on a substrate 7 is formed by having an edge part 6 at a part of the substrate 7. On the substrate 7 to pattern-form the lower part magnetic film 8, the first insulating layer 9 is depositedly formed on the wholesurface, and on the first insulating layer 9, the first electric conductors 1 and 3 are divided into parts and pattern-formd at the upper part area of the edge part 6 of the lower part magnetic film. For such a reason, the film thickness of the first insulating layer 9 comes to be thin at an angle part A, etc., of the lower part magnetic film 8, therefore, the phenomenon such as the short-circuit of the lower part magnetic film 8 and the first electric conductor layer 1 can be prevented. Next, the second electric conductor layer 2 to connect the first electric conductor layers 1 and 3 divided into pieces at the edge part 6 is pattern-formed and in such a case, since the second electric conductor layer 2 is depositedly formed on the second insulating layer 10, the bad influence of the difference in level of the edge part 6 will not be given and the first electric conductor layers 1 and 3 can be connected. |
