To provide a radiation detection apparatus having a structure strong to mechanism stress from the outside which occurs at some midpoint in a manufacturing process and while a product is being used.

An X-ray sensor 300 is sandwiched and fixed between a pressing frame 201 and a damper material 202. An inelastic resin 112 is mounted to a sensor panel 100 correspondingly to a part to be pressed by the pressing frame 201. In its upper part, a fluorescent plate 131; a sheet material 133; and a TCP 122 are simultaneously covered with an elastic resin 113. When the highest part of the elastic resin 113 is matched over a stress-resistant resin, it is satisfactory for the pressing frame 201 to take the form of pressing the inelastic resin from a point at the highest level.
