Summary:To provide a magnetic core that suppresses sound ringing that occurs during driving, an electronic component using the same, and a power supply device using the same.SOLUTION: A magnetic core 1 has a base part 30 extending in a first axial direction, and a pair of outer legs 10,10 protruding from the base part 30 along a second axis perpendicular to the first axis. The relationship between a value of the thickness in the second axial direction Li (mm) of the base part 30 and a value of the height in the second axial direction Lf (mm) having a shorter height in the second axial direction of the pair of outer legs 10,10 satisfies a relationship Li/Lf≥0.45.SELECTED DRAWING: Figure 1A 【課題】駆動時に発生する音鳴りを抑制した磁性体コアと、磁性体コアを用いた電子部品と、電子部品を用いた電源装置を提供すること。【解決手段】第１軸方向に延在するベース部３０と、ベース部３０から第１軸と垂直な第２軸に沿って突出している一対の外脚部１０，１０とを有する磁性体コア１である。ベース部３０の第２軸方向の厚さの値Ｌｉ（ｍｍ）と、一対の外脚部１０，１０のうち第２軸方向の高さが短い方の第２軸方向の高さの値Ｌｆ（ｍｍ）との関係が、Ｌｉ／Ｌｆ≧０．４５の関係を満たすことを特徴とする。【選択図】図１Ａ
