Abstract
An antenna core includes a laminate of a plurality of Co-based amorphous magnetic alloy thin strips in which a length ratio of a long axis to a short axis is greater than 1. 60% or more of the Co-based amorphous magnetic alloy thin strips in terms of the number of the thin strips as percentage have a line-shaped mark formed along the long axis on at least one surface thereof. An antenna includes the antenna core and a winding wound around the antenna core along the long axis.
