BOOSTER ANTENNA BOARD, BOOSTER ANTENNA BOARD SHEET AND NON-CONTACT TYPE DATA CARRIER DEVICE

摘要

PROBLEM TO BE SOLVED: To extend a data communication distance of a non-contact type data carrier, and to use the non-contact type data carrier in the proximity of a conductor such as metal.

SOLUTION: The non-contact type data carrier device 1 includes an antenna layer 7 having a magnetic field converging part 12 for converging an external magnetic field, a booster antenna board 5 provided with a magnetic layer 9 arranged so as to face the antenna layer 7, and a small tag 3 attached to a position (position 12a to be attached) where the magnetic field converging part 12 on the booster antenna board 5 is held between the small tag and the magnetic layer 9.
