According to one embodiment, an electrode is provided. The active material-containing layer includes an active material (50), inorganic solid particles (51) having lithium ion conductivity, and carbon fiber (52). A pore diameter D<sub>M</sub> at 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 represens 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 represens 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. |
