PROBLEM TO BE SOLVED: To provide a radiological image conversion panel giving a radiological image of a high image quality used in a radiological image data recording/reproducing method using a stimulable phosphor. SOLUTION: The radiological image conversion panel including stimulable phosphor particles includes stimulable phosphor particles which is a mixture consisting of a group of stimulable phosphor particles having a relatively large median diameter and a group of stimulable phosphor particles having a relatively small median diameter, and the median diameter of the former group is within a range of 4-30μm and the median diameter of the latter group is within a range of 1-8μm, and further the particle size distribution of the mixture of the two groups satisfies formula (a+b)/5>c, [wherein a and b represents frequency (%) at the peak point on the large particle size side in a particle size distribution curve of the mixture of the stimulable phosphor particles and frequency (%) at the peak point on the small particle size side, respectively, and c represents frequency (%) at the particle size point of the smallest frequency between the two peaks].
