According to one embodiment, an electrode is provided. This electrode includes a current collector and an electrode layer formed on the current collector. The electrode layer contains an active material represented by LiMn1-x-yFexAyPO4 (where 0<x≦̸0.3, 0≦̸y≦̸0.1, and A is at least one selected from the group consisting of Mg, Ca, Al, Ti, Zn, and Zr). A pore diameter appearing at highest frequency in pore diameter distribution of the electrode layer obtained by mercury porosimetry falls within a range of 10 nm to 50 nm. A pore specific surface area of the electrode layer is from 12 m2/g to 30 m2/g. |
