Claims

[Scope of Claim for Utility Model Registration] (1) In a wound core formed by winding magnetic plates in multiple layers to form an iron core, a magnetic material may be applied at any point on the end face of the core from the outer circumferential end to the inner circumferential end. A wound core characterized in that it has a welded part extending all the way to the top. (2) The wound core according to claim 1, wherein the welded portion is provided in a symmetrical arrangement on the end face of the core portion. (3) The wound core according to claim 1 or 2, wherein the welded portion is provided on both end faces of the core portion.
