ABSTRACT OF THE DISCLOSURE A magnetic head having a pair of core half segments opposed to each other face to-face, with a magnetic gap formed therebetween, and bonded to each other with a joint layer. The joint layer is formed by a nonmagnetic oxide layer having a high melting point and extending over the joint faces of the segments. A portion of the nonmagnetic oxide layer functions as the magnetic gap. The nonmagnetic oxide layer is formed by causing a solution of organic metal compound to penetrate into a space between a pair of core half members providing the pair of core half segments and heating the solution to change the solution to a sol and then to a gel and eventually solidify the solution.
