This invention provides a panel body that can be easily assembled by using helical wire members having an excellent working factor. The invention provides also a panel body using helical wire members having excellent impact resistance. Wire members having a predetermined outer diameter are wound in a predetermined lead and pitch to provide a large number of helical wire members in such a fashion that a diameter of a helix is about twice the outer diameter of the wire members, crests and troughs have substantially a similar shape, and each trough is positioned outside the center of helix. A first fixing frame has first fixing bars fitted thereto, which first fixing bars are fitted with predetermined gaps to frame members opposing each other with a predetermined gap between them, and engage with the troughs positioned on the side of one of the surfaces of the helical wire members. Second fixing bars are fitted with predetermined gaps between the frame members of a second fixing frame. When the first and second fixing frames are fixed, the second fixing bars are engaged with the troughs positioned on the other side surface side of the helical wire members, and are clamped and fixed in cooperation with the first fixing bars.
