A toroidal tape core is produced from magnetic sheets (1) which may have slits (4). In order to improve the behavior of the toroidal cores (3) at high frequencies, the magnetic sheets (1) have a high surface roughness. The surface roughness of each magnetic sheet (1) is at least equal to the skin penetration depth at the frequency being used.
