Abstract: Novel cobalt oxyhydroxide is provided with which a positive electrode of an alkaline storage battery having conductivity higher than that of the conventional positive electrodes can be produced, and a method for producing the same is provided. Furthermore, an alkaline storage battery having a high capacity and that can be manufactured easily is provided. The cobalt oxyhydroxide is used for a positive electrode of an alkaline storage battery, in which a first peak corresponding to a crystal plane (003) of the cobalt oxyhydroxide and a second peak corresponding to a crystal plane (012) of the cobalt oxyhydroxide are present on a diffraction line obtained by X-ray diffraction measurement when employing copper Kalpha radiation as a radiation source, a half-power band width of the first peak is 0.6° or less, and a value obtained by dividing a strength of the first peak by a strength of the second peak is 10 or less.
