An alkaline primary battery provided with a positive electrode containing a positive electrode active material and graphite, a negative electrode containing a negative electrode active material, a separator, and an alkaline electrolyte, the positive electrode active material containing manganese dioxide, the alkaline electrolyte containing zinc oxide, and the positive electrode containing metatitanic acid. Due to this, in a battery in which an alkaline electrolyte contains zinc oxide, productions of hetaerolite and the like at the positive electrode and depositions of titanium compound, zinc oxide, and the like on the inner face of a battery case are suppressed, and thus, excellent discharge performance and storage characteristics can be obtained.
