摘要： The purpose of the present invention is to provide a potassium fluoromanganate for use as a raw material for a manganese-activated complex fluoride phosphor, from which a manganese-activated complex fluoride phosphor having good fluorescence properties and reliability can be produced.The potassium fluoromanganate of the present invention is characterized in that, in an orbital electron binding energy spectrum diagram for manganese obtained by X-ray photoelectron spectroscopy, a ratio (signal intensity value A/signal intensity value B) between a signal intensity value A obtained by subtracting a background value from a maximum signal intensity value for binding energy values within the range from 643.0 eV or more to 644.0 eV or less, and a signal intensity value B obtained by subtracting the background value from a maximum signal intensity value for binding energy values within the range from 645.0 eV or more to 646.0 eV or less, is greater than 0 and no greater than 0.9.
