A battery includes an electrode plate group. The electrode plate group includes electrode plates and a separator. The electrode plate group is obtained by laminating a plurality of electrode plates. The separator is disposed between the electrode plates. A surface of at least one of the electrode plates is a particle layer. A surface of the separator is a nonwoven fabric layer. The particle layer includes fibrous particles. The particle layer and the nonwoven fabric layer are in contact with each other.
