To provide a radiation image conversion panel which has high luminance and is excellent in persistence and to provide a method for manufacturing the panel.

When a radiation image conversion panel with a CsBr phosphor layer activated by Eu whose thickness is 300 nm is formed on a crystallized glass support of 1mm thickness by an evaporation method, phosphors which lower a transmissivity of 600 to 700 nm of the radiation image conversion panel after it is irradiated with X rays of 100R to 70% or less of the transmissivity before it is irradiated are selected.
