PROBLEM TO BE SOLVED: To provide a radiographic device capable of fixing a light source emitting light having a wavelength different from that of a radiation and a radiation sensor panel by adhesion and efficiently irradiating a conversion element with the light.SOLUTION: The radiographic device includes a radiation sensor panel 1 which includes a conversion part in which a plurality of conversion elements are two-dimensionally arranged and which converts the radiation or the light into an electric signal, a light source part 4 which includes a light irradiation surface which emits the light having the wavelength different from that of the radiation to the conversion part, a diffusion part 20 which is arranged on at least one of the surface on the side where the light source part 4 is arranged of the radiation sensor panel 1 and the light irradiation surface and diffuses the light emitted from the light irradiation surface, and an adhesive member 5 for adhering the light source part 4 and the radiation sensor panel 1. A gap part 6 is provided between the diffusion part 20 and the adhesive member 5.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 放射線と異なる波長の光を発する光源と放射線センサパネルとを接着により固定し、且つ光を効率よく変換素子に照射することができる放射線撮影装置を提供すること。【解決手段】 複数の変換素子が2次元状に配置され、放射線叉は光を電気信号に変換する変換部を有する放射線センサパネル1と、放射線と異なる波長の光を変換部に発する光照射面を有する光源部4と、放射線センサパネル1の光源部4が配置される側の面及び光照射面の少なくとも一方に配置され、光照射面から発した光を拡散させる拡散部20と、光源部4と放射線センサパネル1とを接着するための接着部材5と、を有し、拡散部20と接着部材5との間に間隙部6を有することを特徴とする放射線撮影装置。【選択図】 図1
