Abstract

A multilayer magnetic sheet comprises a first laminate substrate layer and a second laminate substrate layer, which are stacked in a thickness direction and in each of which laminate substrates each formed in a band shape are arranged in a plate shape such that long sides of the laminate substrates are adjacent to each other, the laminate substrate comprising two or more stacked layers of magnetic ribbons. A direction in which the long sides of the laminate substrates in the second laminate substrate layer extend intersects a direction in which the long sides of the laminate substrates in the first laminate substrate layer extend.
