PROBLEM TO BE SOLVED: To provide a high-frequency multilayer magnetic body which is high in properties such as permeability and saturation magnetization in a high frequency range of a few hundred MHz or above, having a gradient function. SOLUTION: A multilayer film magnetic body is, at least, partially composed of two or more magnetic layers, where a part between the adjacent magnetic layers has a structure formed of a gradient function region possessed of a gradient function of magnetic properties, electrical properties, chemical bonding, or atomic arrangement structure.
