PROBLEM TO BE SOLVED: To provide: a secondary battery improved in ion conductivity; an anion filter used in the secondary battery; and an electrolyte body-electrode assembly capable of being used in the secondary battery.SOLUTION: A secondary battery 10 includes: an electrolyte body 1 including a metal cation and an anion; an anion filter 2 which the metal cation preferentially permeates as compared with the anion; a negative electrode 3 from and/or in which the metal cation is reversibly released and/or stored; and a positive electrode 4 in and/or from which the metal cation is reversibly stored and/or released. In the secondary battery, the negative electrode 3, the electrolyte body 1 and the positive electrode 4 are arranged in the order, the negative electrode 3 and the positive electrode 4 are electrochemically connected by the electrolyte body 1, and the anion filter 2 is disposed in the electrolyte body 1 so as to separate the negative electrode 3 and the positive electrode 4. |
