、非磁性体板５、端子６を有する巻線Ｔからなる。The above-mentioned shield case is used to electromagnetically isolate the internal magnetic head element from the outside and improve the S/N of the magnetic head, and is required to be electrically conductive and have high magnetic permeability. It is made of FeNi-based magnetic material. Today, in order to obtain a high S/N ratio, it is essential to use a -shield case. According to the present invention, an assembly board used in the process of manufacturing a magnetic head can also be used as a shield case without the need to prepare a shield case. The present invention will be explained below with reference to an embodiment of the drawings. In FIG. 1, 1 is a strip-shaped magnetic sheet, and this magnetic sheet 1 is made of the same material as the shield case used in general magnetic heads, such as FeNi-based magnetic material, and is made into a sheet by rolling or other methods. . 2 is a reference hole provided on the magnetic sheet 1 at regular intervals; 3 is a magnetic head element fixed on the magnetic sheet 1 with an adhesive or the like using the reference hole 2 as a reference; this magnetic head element 3 has a core 4
, a non-magnetic plate 5, and a winding T having a terminal 6.

素子３を包持するようにしているために磁気シート１が
シールド板を兼ねることができる。After the magnetic head elements 3 are fixed on the magnetic sheet 1 at predetermined intervals, the magnetic sheet 1 is cut between the magnetic head elements 3. As shown in FIGS. 2 and 3, a non-magnetic plate 8 equivalent to the non-magnetic plate 5 is placed on the core 4, and the magnetic sheet 1 is folded in this state to enclose the magnetic head element 3. A resin such as epoxy is injected into the inside of the magnetic sheet 1 case (magnetic sheet 1) and solidified. Furthermore, the front surface of the magnetic head (the sliding surface of the magnetic tape) is polished to complete the magnetic head. As described above, according to the present invention, the magnetic sheet 1 is used as a base plate, and the magnetic head elements 3 are stacked on top of it for the required number of channels, and in this state, the magnetic head elements 3 are surrounded by the magnetic sheet 1. The magnetic sheet 1 can also serve as a shield plate.
