Abstract
According to one embodiment, an electrode is provided. The active material-containing layer includes an active material, inorganic solid particles having lithium ion conductivity, and carbon fiber. A pore diameter Dat the first peak is 0.05 μm to 10 μm. A value SA−SB is 1.4 or more in a slope distribution curve of the active material-containing layer, where a vertical axis of the slope distribution curve represents a slope of a straight line passing through two adjacent measurement points on the log differential pore volume distribution curve and a horizontal axis of the slope distribution curve represents a smaller pore diameter of the two adjacent measurement points. The value SA−SB is obtained by subtracting a minimum slope value SB from a maximum slope value SA.
