ANTENNA CORE AND METHOD FOR MANUFACTURING THE SAME, AND ANTENNA AND DETECTION SYSTEM USING THE SAME

摘要

An antenna core is provided with a laminate having a plurality of thin strips of Co-based amorphous magnetic alloy, the ratio of the length of the long axis of said thin strips with respect to the length of the short axis being greater than 1. At least 60% of the thin strips (1) of Co-based amorphous magnetic alloy from this plurality of thin strips of Co-based amorphous magnetic alloy, in terms of the number of strips as a percentage, have a line-shaped mark (2A) formed along the long axis on at least one surface thereof. The antenna is provided with an antenna core and a winding that is wound along the long axis thereof.
