PROBLEM TO BE SOLVED: To provide a radiation image converting panel with a high X-ray absorbing coefficient (sensitivity), favorable image quality (small X-ray quantum mottle), and improved WS and MTF. SOLUTION: This radiation image converting panel has a stimulable phosphor layer containing a rare earth activated barium halide fluoride-based stimulable phosphor represented by following general formula (1) and formula (2). General formula (1): Ba1-x M<2> x FBr:yM<1> , zLn General formula (2): Ba1-x M<2> x F1-a I1+a :yM<1> , zLn.
