Abstract
According to one embodiment, an electrode group includes a positive electrode active material-containing layer, a negative electrode active material-containing layer, a lithium ion conductive layer, and a porous layer. The lithium ion conductive layer includes lithium-containing inorganic particles. The lithium ion conductive layer covers at least part of the positive electrode active material-containing layer. The porous layer covers at least part of the negative electrode active material-containing layer. The positive electrode active material-containing layer and the negative electrode active material-containing layer face each other via the lithium ion conductive layer and the porous layer.
