Substrates forming an overlapping portion of an analytical cell have through holes each having a shape tapered from an outer surface of the substrate facing to outside of the overlapping portion toward an inner surface thereof facing to inside thereof. An observation window is formed between the through holes facing each other. In the overlapping portion, at least one of negative and positive electrode active materials is provided between transmission membranes of the observation window, and at least one pillar is provided between first and second positions. At the first position, edge portions of the through holes of the outer surfaces are face-to-face with each other. At the second position, edge portions of the through holes of the inner surfaces are face-to-face with each other. At least one spacer is further provided at a position shifted from the first position toward a circumferential edge of the overlapping portion.
