Generally, the core of electromagnetic induction equipment such as a transformer or a reactor is constructed by processing core sheets made of silicon steel strips, such as grain-oriented silicon steel strips, into a predetermined shape, and then sequentially stacking these sheets. Grain-oriented silicon steel strips have low iron loss, are easy to manufacture into relatively thick and wide strips, and are easy to process and work into the core structure, so they are widely used as core materials for electromagnetic induction equipment. ing.

On the other hand, there is a tape-shaped amorphous magnetic material, for example, which has a lower iron loss than the silicon steel strip mentioned above, but this tape-shaped magnetic material is extremely thin and narrow, and its surface is insulated. No sexual film is formed. As a result, mechanical strength is insufficient, workability is poor, and eddy currents occur between laminated layers during excitation, resulting in increased iron loss. Therefore, it has been difficult to apply it to the core of large-capacity electromagnetic induction equipment.

The iron core sheet according to the present invention has a plurality of tape-shaped amorphous magnetic materials having the same width arranged in a plurality of layers in the width direction. It is constructed by shifting each layer by about 1/2 of the above width and adhering each layer with an insulating adhesive.Multiple core sheets constructed in this way are each processed into a predetermined shape, and then they are laminated one after another. Forms the iron core of electromagnetic induction equipment.
以下図に基づいて説明する。第１図に示すよう

る。 Next, an insulating adhesive is applied to the top surface of each tape-shaped magnetic material 1, and as shown in FIG. The tape-shaped magnetic material 1 is adhered to form the second layer 3. By stacking the tape-shaped magnetic bodies 1 while adhering them in this manner, an iron core sheet 4 having a predetermined thickness is constructed. As a result, a bond having a uniform width can be obtained, and sufficient mechanical strength as a core sheet can be obtained.
