1. A sensor chip for measuring the concentration of an analyte in a blood sample, the sensor chip comprising:

  • temperature electrodes disposed to make contact with the blood sample, the temperature electrodes having at least a working electrode and a counter electrode for measuring a temperature of the blood sample;

    a concentration measuring unit configured to measure a feature related to a concentration of the analyte in the blood sample;

    a sample introduction port; and

    a capillary configured to introduce a blood sample from the sample introduction port to the temperature electrodes and the analysis electrodes,wherein the temperature electrodes are disposed at a position closer to the sample introduction port than the analysis electrodes, andthe concentration measuring unit is formed from analysis electrodes including at least a working electrode and a counter electrode.
