A magnetic head shows a remarkably reduced eddy-current loss. The metal magnetic film 5 of the magnetic core of the magnetic head has a multilayer structure obtained by laying alternately metal magnetic layers 10 and insulating layers 11. The nonmagnetic film 6 of the magnetic head that provides a magnetic gap is also made to have a multilayer structure obtained by arranging first films 20 made of an insulating material, second films 21 made of Cr and a third film 22 made of Au as mentioned from the sides held in contact with the metal magnetic film 5.
