The present invention relates to a method for correcting a biological signal in a continuous biological information measurement system, and more particularly, to a method for correcting a biological signal without directly using a current correction factor calculated from a reference biological value when a correction parameter is unstable when the correction factor is calculated using the reference biological value. Instead, a compensation value calculated from the difference between the current correction factor and the previous correction factor is applied to the current correction factor to correct the current correction factor, so that the biological signal can be accurately corrected to calculate a corrected biological value even if the correction parameter is unstable; the entire use period of the sensor is divided into a plurality of correction intervals, and the correction factor is corrected in consideration of the degree of stabilization of the sensor in accordance with the correction interval to w
