る等の欠点があった。Conventionally, a magnetic head core made of a plurality of laminated core pieces (hereinafter referred to as a laminate core piece) is produced by placing a core piece (1) made of permalloy or the like in a jig, as shown in Figure 1. Laminate and align the layers, then apply adhesive resin such as epoxy resin (
2) was applied and dried and fixed. However, with this structure, the adhesive resin (2) remains attached to the jig when the laminated core half-coated (3) is made, and as a result, the dimensional accuracy of the laminated core half-coated (3) that is performed one after another tends to vary. Additionally, there was a drawback that it took a long time to dry the adhesive resin (2). Furthermore, when the magnetic tape runs over the magnetic head formed using the laminate core half (3), the resin (2) is exposed on the front surface of the magnetic head. However, there were drawbacks such as increased adhesion of magnetic particles.
本発明は上記従来例の欠点を解消せんとするもので、以
下、その１実施例を図面により説明する。The present invention aims to eliminate the drawbacks of the above-mentioned conventional example, and one embodiment thereof will be described below with reference to the drawings.

示すようにラミネートコア半休（３）を形成する。In Fig. 2, (1) is a core thin piece made of a metallic magnetic material such as permalloy or sendust, and (4) is a metal oxide such as 5i02 formed on the surface of the core thin piece fi+ by thin film technology such as vapor deposition or sputtering. A plurality of core flakes (1) provided with this metal oxide (4) are laminated with a metal oxide, and the core flakes (1) are bonded together by anodic bonding.
) and the metal oxide (4) are directly bonded to each other to form a laminate core half-layer (3) as shown in FIG.

℃から７００℃位の温度に設定する。Therefore, anodic bonding is a bonding method shown in Fig. 4. In order to bond an insulating material (5) such as glass and a metal material (6), for example, a heater (blade) is used to bond them. The anode (9) of the power source (8) is heated with a metal material (6), and the negative
This is a method of connecting the two insulators (10) to the insulator (5) and passing a current between them. Uυ is a bonding layer between the two, and 02) is a heater power source. In addition, the heater (7)
The purpose of heating is to increase the electrical conductivity of the insulator (5).
It is not intended to melt the insulator (5), and the
Set the temperature between ℃ and 700℃.

(1) is in contact with the anode of the power source, and the metal oxide (4) is in contact with the cathode to flow a current, and the two are bonded to form a laminate core half-hole (3).
なお、電流値は１μＡ／−〜１ｍＡ／πＡ位で十分で、

気ヘッドを提供し得る。As mentioned above, the present invention forms a laminate core half-hole by directly bonding a core thin piece made of a metallic magnetic material such as permalloy or sendust with a metal oxide by anodic bonding. Compared to the conventional example in which a half-laminated core is formed using resin, the manufacturing process is simpler and time can be reduced.Furthermore, in the finished magnetic head, the resin is not exposed on the tape running surface. Therefore, adhesion of magnetic particles is reduced, and a magnetic head with good characteristics can be provided.
