摘要： In a photoelectric conversion apparatus obtained by arranging and fixing a plurality of semiconductor element substrates onto a base with an adhesive, the levels of the upper surfaces of the substrates are adjusted with a desired thickness of the adhesive so as to set the upper surfaces within the same plane while the distance from the upper surface of the base to the semiconductor element surface of each substrate is kept to a design value, thereby realizing a photoelectric conversion apparatus constituted by a plurality of substrates arranged two-dimensionally, which eliminates level gaps between the substrate, and hence is free from problems such as a decrease in resolution, a deterioration in sensitivity, and peeling of a phosphor and the like.

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.

摘要： In a radiation detection device in which light that is generated at a phosphor layer based on absorbed radiation, the phosphor layer being constituted by connecting side faces of columnar phosphors to each other, is converted into an electric charge at a photoelectric conversion element portion and radiation is detected based on the electric charge, the phosphors have larger column diameters in peripheral regions of the phosphor layer than in a central region thereof. Further, the phosphor layer has a film thickness that is smaller in its peripheral regions than in a central region thereof, thereby preventing breakage of the phosphors.
