Abstract: This electrode comprises: an electrode component containing a columnar structure; and a porous collector layer that is prepared on the electrode component. The columnar structure comprises a multiple columnar sections, the lateral surfaces of which are at least partially in contact with each other. Each columnar part section is provided with a multilayer part wherein different inorganic compound layers are stacked. In addition, the columnar structure comprises two or more adjacent columnar sections, which are different from each other in the stacking direction of the multilayer part. For example, each columnar section has a width of 10 nm to 100 nm, and each inorganic compound layer has a thickness of 1 nm to 10 nm.
