Abstract: A radiological image conversion panel, having a phosphor layer containing therein a fluorescent substance which emits light through radiation exposure, is manufactured by forming the fluorescent substance into respective columnar structures on one of surfaces of a substrate to thereby obtain a phosphor layer made up of a group of columnar structures. The panel is subsequently manufactured by forming reflection films by respectively covering an outer surface of each of the columnar structures with a reflection film while leaving a gap between respective adjoining columnar structures, the reflection film being arranged to reflect light of a predetermined wavelength. In case a refractive index of the gap is lower than a refractive index of the columnar structures, the reflection films are formed of an inorganic material having a higher refractive index than the refractive index of the columnar structures.
