Abstract

An electrode for an electrochemical device has a coated portion in which an active material layer is formed on a current collector; a non-coated portion in which the active material layer is not formed; and a resin layer that is laminated such that the coated portion and a portion of the non-coated portion are covered; wherein: the resin layer has a high-permeability portion having high ion permeability and positioned on the coated portion; a low-permeability portion having low ion permeability and positioned on a portion of the non-coated portion; and a transition portion in which ion permeability decreases from the high-permeability portion side toward the low-permeability portion side and positioned between the high-permeability portion and the low-permeability portion.
