<p>This invention is intended to improve tag read/write accuracy. A tag access device (1) accesses an RFID tag (11) that is provided with a first antenna having radio wave directivity along the longitudinal direction of a plurality of test tubes (10) lined up at prescribed intervals. The tag access device (1) has a multifilar helical antenna (22) which is disposed in a direction directly facing the radio wave directivity of the first antenna, and which has in the center part a field intensity enabling access to the RFID tag (11) when accessing the RFID tag (11).</p> |
