Abstract
A magnetic base body is constituted by: metal magnetic grains containing Fe, and Si as an optional component, where the total content of the Fe and Si is 99% by mass or higher; and oxide layers present between the metal magnetic grains; wherein the ratio (I/I) of the strongest diffraction line intensity (I) observed in a range of 30.8°≤2θ≤32.2° to the strongest diffraction line intensity (I) observed in a range of 43.8°≤2θ≤45.2° in X-ray diffraction measurement using the CuKα ray is 0.0020 or higher; and the ratio (I/I) of the strongest diffraction line intensity (I) observed in a range of 33.0°≤2θ≤34.4° to the Iin X-ray diffraction measurement using the CuKα ray is lower than 0.0010.
