<p>PROBLEM TO BE SOLVED: To provide a magnetic core which has synthetically low loss as an inductance component little heat generation caused by a high frequency current, by considering hysteresis loss and conduction loss of winding. SOLUTION: This magnetic core is provided with a bottom plate 13 of a rectangular paralleopiped, outer legs 12 which are formed integrally with the bottom plate on both end portions of a long side on one surface of the bottom plate and a center leg 11 which is formed integrally with the bottom plate, in the central part of the bottom plate in such a manner that the long axis direction coincides with the direction of the long side of the bottom plate, and makes a pillar having a rectangular section. The distance between the side surface of the center leg and the inner side surface of the outer leg is constant. The length of the long side of the bottom plate part is at least 1.0 time and at most 1.5 times the length of the short side of the bottom plate and at least 1.2 times and at most 2 times the long axis of the center leg.</p> |
