PROBLEM TO BE SOLVED: To provide a data carrier and a non-contact identification information management system that enhance reliability and selectively suppress leakage of data.SOLUTION: A data carrier 10 includes at least an antenna coil 23, and at least part of a wound line of the antenna coil 23 is formed of a soft magnetic material. In addition, a non-contact identification information management system 100 comprises: the data carrier 10 including the antenna coil 23; and a reader/writer 40 that reads and writes identification information held by the data carrier 10 by an electromagnetic induction system via an antenna 30 including an antenna coil 33. At least part of the line of the antenna coil 23 or the antenna coil 33 is formed of a soft magnetic material. The non-contact identification information management system also comprises communication permission means for applying a magnetic field to the soft magnetic material.SELECTED DRAWING: Figure 1 【課題】信頼性を高めて、選択的にデータの漏洩を抑制するデータキャリア及び非接触識別情報管理システムを提供する。【解決手段】データキャリア１０は、少なくともアンテナコイル２３を有し、アンテナコイル２３は、巻回する線路の少なくとも一部が軟磁性材料である。また、非接触識別情報管理システム１００は、アンテナコイル２３を有するデータキャリア１０と、アンテナコイル３３を有するアンテナ３０とが電磁誘導方式によりデータキャリア１０が保持する識別情報を読み書きするリーダライタ４０を備え、アンテナコイル２３又はアンテナコイル３３は、線路の少なくとも一部が軟磁性材料であり、軟磁性材料に磁界を印加する通信許可手段を備える。【選択図】図１
