1. A biological information measurement device, to which a biosensor is attached, the biosensor having a first electrode, a second electrode, and a reagent portion provided between the first electrode and the second electrode,wherein the biological information measurement device comprises:

  • a first input terminal, to which the first electrode is connected, and a second input terminal, to which the second electrode is connected;

    a voltage applying unit for applying a voltage to the first input terminal and the second input terminal; and

    a control unit connected to the voltage applying unit, the first input terminal, and the second input terminal,the control unit is configured to execute a biological information characteristic detection mode and a biological information measurement mode following the biological information characteristic detection mode,during the biological information characteristic detection mode, with respect to the voltage applying unit, the control unit applies different voltage values between the first input terminal and the second input terminal from the voltage applying unit in a first period and a second period of the biological information characteristic detection mode and detects currents flowing between the first input terminal and the second input terminal in the first period and the second period,the control unit calculates a biological information correction value from the currents flowing between the first input terminal and the second input terminal in the first period and the second period, andthe control unit corrects a biological information measurement value measured by the biological information correction value during the biological information measurement mode.
