PURPOSE:To prevent electrolytic corrosion by interposing a polyaramid sheet between a carbon fiber-reinforced plastic and an aluminum alloy. CONSTITUTION:A radiation incident window is provided in the radiation incident direction of a pressure vessel 1A made of an aluminum alloy, a detector window member 2 is mounted thereon and a holding frame 8 made of aluminum alloy, for instance, is provided to reinforce. The detector window member 2 is so arranged to interpose a polyaramid sheet 4 as binder between the pressure vessel 1A made of an aluminum alloy and a carbon fiber-reinforced plastic 3.
