To provide an electrode for a secondary battery which is used as a cathode or an anode of a secondary battery.SOLUTION: An electrode for a secondary battery is provided which comprises an electrolytic solution, or a solid or gelatinous electrolyte, the electrode further comprises a current collector 222 including electrically conductive substance and an active substance layer 224 in contact with at least a part of the current collector and including an active substance. In at least either the current collector or the active substance layer of the electrode for a secondary battery, ion permeation regions 462, 464 each at least having either a gap that allows electrolyte ions of the electrolytic solution to be entered therein or an ion conducting substance having an ion transport number higher than that of the active substance are disposed. The ion permeation region may be disposed at positions where the electrolytic solution or the electrolyte of the secondary battery can come into contact with a surface of the active substance when the electrode for a secondary battery is assembled in a secondary battery.SELECTED DRAWING: Figure 4
