Abstract

According to one embodiment, an electrode is provided. The electrode includes an active material-containing layer. The active material-containing layer includes: an active material including a titanium-containing composite oxide; inorganic solid particles having lithium ion conductivity; and carbon fiber. The active material-containing layer has a first peak indicating a maximum log differential pore volume in a log differential pore volume distribution curve according to mercury porosimetry. A pore diameter PD at the first peak is 0.01 μm to 0.1 μm. The first peak has a full width at half maximum of 0.05 μm or less.
