Saddle coils are manufactured by placing wires in grooves formed in a first mold, so that the spatial arrangement of the saddle coils are determined by the positions of the grooves. This enables the wires to be precisely located in predetermined positions and assures a precise spatial arrangement of the saddle coils. Further, the wire is held by guides to form a solenoid coil. With this arrangement, high positional accuracies of the saddle coils and the solenoid coil are obtained, improving the detecting accuracy of the slice position of an object to be examined.

A radiation detector has a housing in which is sealed a gas to be ionized when X-rays are projected therein. A plurality of electrodes for detecting the X-rays are arranged in the housing, and the housing is curved with a fixed curvature along the arranged direction of the electrodes. A vessel portion of the housing is closed by a cover portion. A cut extending in the longitudinal direction of the housing is formed in one side wall of the vessel portion. The cut is closed by an X-ray window. A window member of the X-ray window is made of carbon fiber reinforced plastics. The window member is bonded to the inside face of the side wall of the vessel portion, and is pressed against the inside face by the pressure of the gas sealed in the housing. Thus, the window member and the vessel portion are fully hermetically sealed. Since the X-ray transmission factor of the carbon fiber reinforced plastics is high, even low-energy X-rays can be projected with high intensity between the electrodes.
