Abstract
A tag access apparatus accesses an RFID tag provided with a first antenna having a radio wave directivity along a longitudinal direction of a plurality of test tubes arranged at a predetermined interval. The tag access apparatus has a multi-filler helical antenna which is provided in a direction opposite to the radio wave directivity of the first antenna and which maintains an electric field strength at a central part of the multi-filler helical antenna at a level that allows access to the RFID tag, at the time of access to the RFID tag.
