Abstract
An electrode includes a base material and an active material layer. The active material layer is disposed on a base material surface. One or more grooves are formed on an active material layer surface. The one or more grooves linearly extend along the surface of the active material layer. In a plan view, each of the one or more grooves includes an inlet region, an intermediate region, and an outlet region. Each of the inlet region and the outlet regions is configured such that a first pressure loss occurring when a fluid flows in a forward direction is smaller than a second pressure loss occurring when the fluid flows in a backward direction.
