Abstract
A multilayer magnetic sheet comprises laminate substrates each comprising two or more stacked layers of band-shaped magnetic ribbons. The laminate substrates are arranged side by side in a plate shape in a direction in which long sides of the laminate substrates are adjacent to each other and short sides of the laminate substrates extend. The plate shapes each provided by the laminate substrates arranged side by side are stacked in a thickness direction of the laminate substrate. Ten or more layers of the magnetic ribbons are stacked in total. Positions of the long sides of the laminate substrates adjacent to each other in a direction in which the laminate substrates are stacked are different and separated from each other by 0.5 mm or more in the direction in which the short sides extend.
