<p>To achieve improvement in accuracy in reading and writing of a tag. A tag access apparatus (1) accesses an RFID tag (11) provided with a first antenna having a radio wave directivity along a longitudinal direction of a plurality of test tubes (10) arranged at a predetermined interval. The tag access apparatus (1) has a multi-filler helical antenna (22) 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 (22) at a level that allows access to the RFID tag (11), at the time of access to the RFID tag (11).</p> |
