The energy density, high output density is high dose provides high stability of a lithium ion capacitor. As a lithium ion capacitor provided with the lithium salt aprotic organic solvent solution as a positive electrode, a negative electrode and an electrolyte, the positive electrode active material is capable of reversibly carrying lithium ion and an anion material, and also possible negative active material is reversibly carry lithium ion material , as a lithium ion capacitor that is less than 2.0V potential after the positive electrode and the negative electrode were short-circuiting the positive electrode and the negative electrode, the positive electrode and the negative electrode on both sides of a positive electrode collector and the negative electrode current collector having a hole penetrating the respective front and rear surfaces, each anode is made by forming an electrode active material and a negative electrode active material, the positive electrode and the negative electrode has a cold or a stacked cell configuration, the outermost winding or a lithium ion capacitor, characterized in that the cathode of the stacked electrodes. Negative electrode potential, a lithium ion capacitor, the current collector, the active material
