特開昭６２−２２３８０６で記述されている。2. Description of the Related Art Thin film magnetic heads used in conventional magnetic recording and reproducing devices for storage devices such as computers are usually manufactured by the steps shown in FIGS. 2 to 4. That is, two magnetic plates 1 and 2 made of ferrite, which is a core material with a thin film winding or a non-magnetic film formed on at least one side, are butted against each other using a jig 4 as shown in FIG. Adhesive is injected and heated in a furnace to form a bond. Thereafter, as shown in FIG. 3, the bonded chip is polished or shaped into a curved surface as shown by dotted line 8 to obtain the magnetic head shown in FIG. 4. Such a manufacturing method includes, for example,
It is described in Japanese Patent Application Laid-Open No. 62-223806.

When the adhesive is injected after the magnetic plates 1 and 2 are butted together using the jig 4, the viscosity of the adhesive is low due to the narrow gap between the magnetic plates (if not, the entire contact area of the chip Since the viscosity is low, it unfortunately invades the bonding land 8 of the head core shown in FIG. 3 due to capillary action, leading to poor bonding, which is extremely difficult to prevent. In other words, the adhesive covers all or part of the bonding land, which obstructs the wire bonding of the flexible printed circuit board, which is the connection line for the magnetic head, and the adhesive on the bonding land must be removed separately during the wire bonding process. This requires complicated work to remove using a treatment method, which poses a problem of poor work efficiency.

ものである。In order to achieve the above object, the present invention abuts two magnetic plates using a jig, and before injecting an adhesive into the gap between the two, a highly viscous ultraviolet curable resin or Apply a masking agent such as resist, harden it with heat or ultraviolet light, etc.
The bonding land is temporarily protected by an adhesive, and the masking agent is removed from the head core using an organic solvent or mechanically during wire bonding work with the connection line.
