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.
