摘要

Disclosed is an electrochemical element comprising two or more active material layers between a pair of electrodes, wherein two layers that are substantially adjacent to each other among the two or more active material layers are formed from active materials different from each other, and at least one of the two layers contains fine particles composed of the active material. In addition, the two active material layers are laminated without having an electrolyte layer therebetween.
