A method for appropriately managing the quality and distribution of a probe carrier. Probe carriers manufactured by a probe carrier manufacturing apparatus having ejecting portions for ejecting probe solutions, each containing a probe, which can be specifically coupled with a target substance, for applying the probe solution on a carrier, and a plurality of probe tanks storing mutually different probe solutions for supplying ejecting portions. Each probe tank is labeled with the bar-code. The labeled bar-code is read by the bar-code reader. On the basis of the read bar-code, the probe solution stored in the probe tank is identified. On the other hand, the probe tank is mounted on the ejecting portion.
