PROBLEM TO BE SOLVED: To provide a producing method of radiation image conversion panel superior in sharpness and graininess. SOLUTION: Whole process is constituted of at least a phosphor sheet forming process forming a phosphor sheet consisting of combining agent and stimulable phosphor, a layering process for obtaining layering body by layering without adhering and fixing the phosphor sheet onto a support, and a heating and compressing process for compressing the phosphor sheet and adhering to the support by pressing the obtained layering body at a temperature over softening temperature or the melting point of the combining agent. The heating and compressing process is a process for inserting in the nip part of a pair of heated and pressed rolls. The temperature of the roll surface in contact with the support side surface of the layering body is set higher than that of the roll surface of the phosphor sheet side.
