Abstract
The electrode according to an embodiment includes an electrode layer and an organic fiber-containing layer. The organic fiber-containing layer is provided on the electrode layer. The organic fiber-containing layer includes an organic fiber. The organic fiber-containing layer has a ratio tW/tD within a range of 1.1 to 2.55, where tW is a thickness [μm] in a wet state and tD is a thickness [μm] in a dry state. A ratio dW/dD is within a range of 0.95 to 1.05, where dW is an average fiber diameter [nm] of the organic fiber included in the organic fiber-containing layer in the wet state, and dD is an average fiber diameter [nm] of the organic fiber included in the organic fiber-containing layer in the dry state.
