(57) This concrete structural body comprises concrete, and an RFID device contained in the concrete. The RFID device comprises a capsule, and an RFID tag which is disposed inside the capsule, operates upon receipt of a prescribed call signal, and transmits a prescribed response signal. The capsule is configured such that a rupture exposing the RFID tag to the outside of the capsule occurs if an external force exceeding a prescribed force is applied. The RFID tag is configured to change to an incommunicable state upon coming into contact with a component of the atmosphere.
