A method for manufacturing a lithium ion capacitor, and a lithium ion capacitor manufactured using the method are provided. The method for manufacturing a lithium ion capacitor includes: disposing a lithium metal on a capacitor cell including a cathode, a separation film, and an anode; impregnating the capacitor cell with electrolyte including a lithium salt; changing the cathode and the anode to allow lithium ions within the electrolyte to be occluded into the anode; performing a primary reaction in which the cathode and the lithium metal are short-circuited to emit anions from the cathode and lithium ions from the lithium metal and a secondary reaction that the lithium ions emitted from the lithium metal are occluded into the cathode; and recharging the cathode and the anode to allow the lithium ions, which have been occluded into the cathode and the lithium ions within the electrolyte, to be occluded into the anode.
