Abstract: An electrochemical device includes a power generating element, an outer package, a current collector, and a movement restricting member. The power generating element includes a main portion and a terminal portion. The main portion includes an electrode prepared by forming an active material layer on a metal foil surface of the electrode. The terminal portion is provided on a side of the main portion. The outer package houses the power generating element. The current collector is connected to the terminal portion of the power generating element. The movement restricting member includes a holding portion arranged between the side of the main portion of the power generating element and an inner surface of the outer package opposite the side of the main portion.
