Abstract

PURPOSE:To improve the reliability, by forming two-layer of ferromagnetic metallic thin film with different permeability to a ferromagnetic thin film forming face whose bonding face is tilted to a magnetic gap to be formed between both half cores so as to reduce the effect of pseudo gap. CONSTITUTION:The magnetic core halves 1 are made of a ferromagnetic oxide such as Mn-Zn-series ferrite and a 2nd ferromagnetic metallic thin film 2 and a 1st ferromagnetic metallic thin film 6 made of Fe-Si-Al series alloy are bonded to the ferromagnetic thin film forming face with the bonding face of the magnetic core halves 1 tilted continuously from the front gap forming face to the back gap forming face by the vacuum thin film forming technology. The ferromagnetic metallic thin film 6 with different permeability is formed between the core halves 1 and the ferromagnetic metallic thin film 2 with different forming condition to increase the bonding strength with the core halves 1 and the influence of pseudo gap in the forromagnetic thin film forming face 1a is reduced.
