1. A quantitative analyzing method for electrochemically measuring concentration of a substance in a sample liquid using a sensor including a reagent layer which contains a reagent for reacting with the substance and to which the sample'"'"' liquid is introduced, and a first and a second electrodes for applying a voltage to the reagent layer, the method comprising:

  • a current measuring step for applying a voltage across the first electrode and the second electrode for measuring current flowing between the first electrode and the second electrode;

    a parameter calculating step for calculating a parameter based on the measured current; and

    a determining step for determining whether or not the sample liquid introduced to the reagent layer is insufficient in amount based on the parameter and at least one predetermined constant.
