To provide a metal magnetic thin plate laminated core of low loss and a high Q value in an electronic component using a magnetic core using a metal magnetic material.
For the magnetic core, magnetic thin belts 11 composed of a conductive magnetic material are laminated through insulation layers 12. The magnetic core is provided with two main surfaces composed of the magnetic thin belts and four main surfaces composed of laminated cross sections, and the area of the main surfaces composed of the magnetic thin belts among them is smaller than the area of at least one main surface composed of the laminated cross section. Also, the magnetic core is formed by arranging the plurality of magnetic materials in a line shape or a strip shape parallelly in longitudinal and lateral directions mutually through an insulation material, and each magnetic material in the line shape or the strip shape is continuous between two end faces of the magnetic core.
