Abstract

PURPOSE:To reduce lowering of the magnetic characteristic accompanied with curing of resin and movement of the core due to the secular change, by making it needless to charge the adhesive resin by fixing the core holder and the shield case by melt-sticking. CONSTITUTION:Coils 2 are wound around core half materials 1 consisting of materials having high magnetic permeability such as Permalloy, and these core half materials 1 are held by core holder 3 of the Cu-Zn alloy and are butted to each other, and a part of core half material 2 is exposed to the outside of core holder 3. Core holder 3 is inserted into shield case 4 using Permalloy materials from the arrow A direction, and the silicon resin is charged. Welding using microplasma is performed in the joined part of core holder 3 and shield case 4 to form melt-stuck parts 5a-5f. Since, the resin which is charged in shield case 4 to fix core holder 3 does not need adhesive force, the silicone resin is used.
