Abstract
An electrode loss measuring apparatus includes an electrode which moves in a roll-to-roll state between an unwinder and a rewinder and on which a plurality of reference points are marked at predetermined intervals. The apparatus further includes a reference point detector configured to detect the reference points marked on the electrode, a position measurer configured to derive a position value of the electrode according to a rotation amount of the unwinder or the rewinder and a position value of the corresponding reference point in conjunction with the reference point detector when the reference point detector detects the reference point, and a calculator configured to calculate a loss amount of the electrode by comparing the derived position value of the reference point with a position value of a set reference point when an interval between the reference points is changed due to a loss of a portion of the electrode.
