PURPOSE: To obtain a magnetic head in which the bonding strength of core members and the corrosion resistance of a head core are improved, by forming a surface layer made of Ni, Cr, Cu or Ti on the surface of each core member and laminating the core members with lamination.
CONSTITUTION: An amorphous ferromagnetic alloy of an amorphous ferromagnetic alloy material, e.g. Fe-Co-Si-B system is formed in ribbon shape, and a core member 2 of a specified shape is formed from an amorphous ribbon 1. In a head core of a magnetic head, a plurality of punched core members 2a, 2b and 2c are formed with lamination. On the surface of each core member 2, one or more types of Ni, Cr, Cu and Ti are attached to the surface of the core member 2 as the surface layer 3 with plating, vapor-deposition or sputtering. After forming the surface layer 3 on the surface of each core member, the core members 2a, 2b and 2c are laminated and bonded with an adhesive 5.
