Abstract
To inhibit degradation of charge and discharge cycle characteristics of a secondary battery. To suppress generation of defects due to expansion and contraction of an active material in a negative electrode. To inhibit deterioration of an electrode due to changes in its form. An electrode member including a current collector, an active material, and a porous body is used. The porous body is in contact with one surface of the current collector and includes a plurality of spaces. The active material is located in the space in the porous body. The space has a larger size than the active material.
