Abstract

PURPOSE: To make the deposition in a specified narrow portion possible by yielding hightly compressed area on the parts of a plurality of laminated thin plates and heating them.
CONSTITUTION: Protruded portions 3a are provided on the part of a thin plate 3 made of a high-permiability material by press machining, and a plurality of the thin plates are laminated. When the plates are compressed from the directions of A and B, the pressure at the compressed portion 4a is higher than the pressure at the opposing portion 4b. When a plurality of the thin plate 3 are heated at 1,000°CW 1,200°C under this condition, only the highly compressed portion 4a is deposited. When cooled, the laminated thin plates 3 become unseparatable, and a magnetic core 5 is obtained.
