<p>In an electronic cassette (10), an FPD (17) and a support substrate (19) are accommodated in a housing (15). A signal processing circuit for processing signals from the FPD is formed in a circuit board (18). The circuit board is attached to the back of the support substrate. The support substrate is a carbon plate made from carbon fiber reinforced plastic and exhibits anisotropy in bending strength depending on a fiber direction of carbon fiber. Spacers (37a-37d) are provided inside a rear case (23) that constitutes the housing. The spacers form a space, between the support substrate and the housing, to accommodate the circuit board. The spacers are arranged to suppress or prevent bending of the support substrate in a direction of weak bending strength.</p> |
