<P>PROBLEM TO BE SOLVED: To provide an electronic cassette for radiograph that hardly causes temperature unevenness within a detection surface of a detection unit which is caused by heat transmitted from a transmission plate of a housing even when an ISS (Irradiation Side Sampling) method is employed. <P>SOLUTION: The electronic cassette is a cassette for detecting an image having a half-cut size (383.5 mm×459.5 mm), and a planar shape of a transmission plate 27 is rectangular. The transmission plate 27 is constructed by two kinds of a high thermal conductivity layer 81 and a low thermal conductivity layer 82, and the high thermal conductivity layer 81 is arranged on an upper layer. The high thermal conductivity layer 81 has anisotropy so that thermal conductivity within a rectangular surface is higher in a longitudinal direction than in a lateral direction. Heat is easily diffused within the surface of the transmission plate 27 by arranging the high thermal conductivity layer 81 on the upper layer and the low thermal conductivity layer 82 on a lower layer. Further, a heat diffusion area within the rectangular surface can be used effectively by providing a difference of the heat conductivity between in the longitudinal direction and in the lateral direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
