PROBLEM TO BE SOLVED: To enhance characteristics such as a communication range and communication sensitivity and also to enable a non-contact data carrier package to make communication in the case of being arranged perpendicularly to an antenna coil of an interrogator side when the non-contact data carrier package is formed into a thin package like a card shape. SOLUTION: An antenna magnetic core 13 consisting of a plane body obtained by laminating one or more layers of thin plate magnetic materials in which permeability is >=500 at 100 kHz is inserted into an air-core part 12a of an antenna coil 12 consisting of an air-core coil. The antenna magnetic core 13 is arranged so as to substantially form the same plane as that of the antenna coil 12 while being inserted into the air-core part 12a of the antenna coil 12. The antenna coil 12 is electrically connected to a circuit component 15. These antenna magnetic core 13, antenna coil 12 and circuit component 15 are sealed/ integrated with sealing material such as an exterior sheet 18 so as to form, e.g. a card shape. |
