Zusammenfassung:PROBLEM TO BE SOLVED: To form an alignment marker for accurately positioning upper and lower layer elements constituting a recording head. SOLUTION: In the magnetic head element formed by laminating a reproducing head 1 and a recording head 2 as upper and lower layers, the recording head 2 is formed on the upper shield part 10 of the reproducing head 1 polished to be flat, an alignment marker 14 is formed on a recording magnetic gap 12 formed on the upper shield part 10, and the alignment marker 14 is a three- dimensional structure having a corner part of a film thickness direction to serve as a positioning marker during thick film forming on at least the recording magnetic gap 12.
