The purpose of the present invention is to provide an electrode for a lithium-ion cell having an excellent electron conductivity even when the thickness of the electrode is increased. This electrode for the lithium-ion cell is provided with a first main surface disposed on the separator side of the lithium-ion cell and a second main surface disposed on the collector side of the lithium-ion cell; wherein said electrode is characterized by having a thickness of 150-5000 micrometers and containing an electroconductive member (A) made of an electron-conducting material and a large number of active material particles (B) between the first main surface and the second main surface, at least a part of the electroconductive member (A) forming an electroconductive channel for electrically connecting the first main surface and the second main surface, and the electroconductive channel being in contact with the active material particles (B) around the electroconductive channel.
