Abstract
To solve a problem that in a battery having a negative electrode having a capability of releasing a metal ion, a positive electrode for causing a liquid such as water or seawater to contribute to battery reaction, and an inorganic solid electrolyte, the inorganic solid electrolyte contacts the positive electrode for a long term, whereby a deterioration is generated from the interface between the electrolyte and the positive electrode so that the battery capacity falls or the battery cannot give a high power. The positive electrode and the inorganic solid electrolyte are not brought into contact with each other. Preferably, the interval between the positive electrode and the electrolyte is set to 0.3 nm or more.
