1. A scintillator panel comprising a substrate, a grid-like barrier rib formed on the substrate, a phosphor layer in cells divided by the barrier rib, and a reflective layer surrounding the side and the bottom of the phosphor layer, the scintillator panel comprising a part where the reflective layer surrounding the side of the phosphor layer is curved and a part where opposing surfaces of the reflective layer at the side of the phosphor layer are approximately parallel, wherein a partition auxiliary layer is provided between the barrier rib and the reflective layer,
wherein a ratio in a width direction of a part where the reflective layer at the bottom of the phosphor layer is curved to a part where the reflective layer at the bottom of the phosphor layer is flat is 10.0:0 to 1.0:9.0, and
a ratio in a thickness direction of the part where the reflective layer surrounding the side of the phosphor layer is curved to the part where opposing surfaces of the reflective layer at the side of the phosphor layer are approximately parallel is 0.5:9.5 to 7.0:3.0.
