1. An apparatus for detecting a stacking direction of internal electrodes of a multilayer capacitor, the apparatus comprising:
a capacitor moving unit having a supply unit in which a plurality of multilayer capacitors are continuously supplied and moving the supplied multilayer capacitors in one direction;
a sensor unit including a coil, installed on the capacitor moving unit, and configured to detect inductance of the coil when each of the multilayer capacitors approaches the coil and to determine a stacking direction of internal electrodes of the corresponding multilayer capacitor based on the detected inductance of the coil; and
a separating unit installed on the capacitor moving unit and configured to separate a multilayer capacitor selected as an unsuitable multilayer capacitor by the sensor unit.
