Provided is a lithium air secondary cell in which degradation of the alkali electrolytic solution, air electrode, and negative electrode can be effectively prevented and which has a long lifespan and a high long-term reliability. The lithium air secondary cell is provided with: an air electrode (12) that functions as a positive electrode; a negative ion exchanger (14) which is provided in intimate contact with one surface side of the air electrode and which comprises a hydroxide-ion-conducting inorganic solid electrolyte; a separator (16) which is provided at a distance from the negative ion exchanger and which comprises a lithium-ion-conducting inorganic solid electrolyte; a negative electrode (18) which is provided so as to be capable of transferring lithium ions to and from the separator and which includes lithium; and an alkali electrolytic solution (20) packed between the negative ion exchanger and the separator. |
