| 1. A measurement instrument which is attached to a concentration measuring device for calculating a concentration based on
concentration calculation information and is capable of outputting the concentration calculation information to the concentration
measuring device, the measurement instrument comprising,
a working electrode,
a counterpart electrode paired with the working electrode,
a reagent part bridging between the working electrode and the counterpart electrode, and
an attribute information output section for outputting attribute information relating to an attribute of the measurement instrument
as an electric physical quantity,
wherein the attribute information output section comprises a plurality of attribute-indicating electrodes provided in addition
to the working electrode and the counterpart electrode, and a plurality of connection-breakable parts bridging between the
attribute-indicating electrodes, and
wherein the attribute information correlates with a resistance of the attribute information output section.
