Patent Number: 
Section: claims

1. A scintillator panel comprising:a supporting substrate which transmits a radiation ray;a reflective resin sheet formed directly on top of one face of the supporting substrate, the reflective resin sheet having a single layer made from foamed resin; anda phosphor layer which is formed directly on top of the reflective resin sheet disposed on the one face of the supporting substrate and converts the radiation ray into visible light. 2. A radiation detector comprising:an image sensor having a plurality of photoreceptor elements arranged thereon; andthe scintillator panel according to claim 1 in combination of the image sensor. 3. A scintillator panel comprising:a supporting substrate which transmits a radiation ray;a reflective resin sheet formed on at least one face of the supporting substrate, the supporting substrate being made of carbon fiber-reinforced plastic (CFRP) impregnated with thermosetting resin, the reflective resin sheet having a single layer, the single layer being an expanded resin layer or dispersed with a grain of heterogeneous substance different from the resin in the resin sheet; anda phosphor layer which is formed on the reflective resin sheet on one face of the supporting substrate and converts the radiation ray into visible light,wherein the reflective resin sheet is bonded by resin, which is originally impregnated in a base material of CFRP before heat curing, to the CFRP supporting substrate. 4. A radiation detector comprising:an image sensor having a plurality of photoreceptor elements arranged thereon; andthe scintillator panel according to claim 3 in combination of the image sensor.
