Abstract
A number of C-FRP molded material sections that are elongated and made from a carbon fiber reinforced plastic are placed parallel to each other. The C-FRP molded material sections are insulated from each other by honeycomb material sections that are made from an insulating and nonmagnetic material. The C-FRP molded material sections and the honeycomb material sections are maintained by a glass fiber layer into a sheet plate shape.
