PROBLEM TO BE SOLVED: To provide an electrode that has a high filling density of an active material and increases energy density, and to provide an electrochemical device using the electrode. SOLUTION: The electrode contains at least the active material, a conduction assistant, and a fluorine-containing binder for binding the active material with the conduction assistant. In the electrode, a fluorine ratio Y(=B/A) of the content of fluorine on a surface whose strength is the weakest in the electrode to that A of fluorine on the surface of the electrode, and a filling amount X(90 wt.%≤X≤97.5 wt.%) of the active material in the electrode are in a relationship of Y≥0.046X-3.905.
