PROBLEM TO BE SOLVED: To provide a magnetic core for which a required flange installation space and a practical excess space can be secured even within a narrow mounting area, a magnetic component and a designing method of the magnetic core.SOLUTION: An outline OL1 of a cross section P of a flange 12 is formed in a first irregular convex polygonal shape which is an irregular polygon and a convex polygon, and includes a side Sa1 and a side Sa2 brought into contact with all sides Sb1-Sb4 of a first circumscribed rectangle RC1 which is circumscribed with the outline OL1, and overlapped partially with the sides Sb1 and Sb2, respectively. The cross section P includes corner cuts Ca1 and Ca2, and corner cuts Ca3 and Ca4 which are set in size equal to or less than 1/2 of the corner cuts Ca1 and Ca2, in each end portion of diagonals Db1 and Db2 of the first circumscribed rectangle RC1, respectively.SELECTED DRAWING: Figure 4 【課題】狭小な実装領域内においても、必要な鍔部設置用スペースと有用な余剰スペースを確保することが可能な磁性コアおよび磁性部品と、磁性コアの設計方法を提供する。【解決手段】鍔部１２の断面Ｐの輪郭線ＯＬ１は、非正多角形でかつ凸多角形である第１の不規則凸多角形の形状をなすように形成され、この輪郭線ＯＬ１と外接する第１の外接長方形ＲＣ１の辺Ｓｂ１〜Ｓｂ４の全てに対して接し、かつ辺Ｓｂ１およびＳｂ２の各一部とそれぞれ重なる辺Ｓａ１および辺Ｓａ２を有している。また、断面Ｐは、隅切部Ｃａ１およびＣａ２と、これらの２分の１以下の大きさに設定された隅切部Ｃａ３およびＣａ４を、第１の外接長方形ＲＣ１の対角線Ｄｂ１およびＤｂ２の各端部に、それぞれ有している。【選択図】図４
