Electrochemical corrosion of a reflective layer provided in a scintillator panel is prevented. The scintillator panel includes a conductive base member for supporting a wavelength converter layer and a reflective layer for emitting light converted by a phosphor layer to the outside, in which an insulating layer is formed between the conductive base member and the reflective layer. Alternatively, the above problem is solved by a scintillator panel in which the full circumference including the base member surface side of the reflective layer, the wavelength converter layer side of the reflective layer, and end surfaces of the reflective layer is covered with an insulating layer or a protective film for the reflective layer and a radiation imaging device using such a scintillator panel.
