PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode, where occlusion of lithium to an electrode active material progresses uniformly at a low cost, and to provide a power storage device and a device.SOLUTION: A method of manufacturing an electrode includes (A) a step for reducing the pressure in a chamber housing a collector in which a layer containing an active material (hereinafter, referred to (active material layer)) is formed, and a lithium supply source, (B) a step for supplying an organic solvent containing lithium ions into the chamber subjected to pressure reduction, and (C) a step for making the active material occlude lithium. Consequently, an electrode where the entire active material is doped uniformly with lithium can be obtained, and it is very useful in the manufacture of the electrode of a battery or a capacitor, such as a lithium ion secondary battery, an air battery, a lithium ion capacitor, and the like.SELECTED DRAWING: None 【課題】低コストで且つ電極活物質へのリチウムの吸蔵が均一に進む電極の製造方法、蓄電デバイス及び装置を提供する。【解決手段】電極の製造方法は、（Ａ）活物質を含む層（以下「活物質層」ともいう。）が形成された集電体及びリチウム供給源を収納したチャンバー内を減圧する工程、（Ｂ）前記減圧したチャンバー内にリチウムイオンを含む有機溶媒を供給する工程、並びに（Ｃ）前記活物質にリチウムを吸蔵させる工程を含む。これにより、活物質全体にリチウムが均一にドープされた電極を得ることができ、リチウムイオン二次電池、空気電池、リチウムイオンキャパシタ等の電池又はキャパシタの電極の製造に極めて有用である。【選択図】 なし
