SOLUTION: In an antenna guide mallet 10, a tube formed, by spirally winding a sheet material 20b, is arranged on the outer periphery of a tube formed with spirally winding the sheet material 20b. The tubes are bonded in a state where they are arranged, so that the joints of the tubes are shifted, and they are of one tube. In a sheet member 20, an aluminum foil 21 as a metal layer is disposed, a PET film layer 22 is laminated on the surface side of the aluminum foil 21, and the PET film layer 22 is also laminated on the rear side. A polyethylene film layer 24 is laminated on the PET film layer 23 arranged at the rear side. The overlapped polyethylene film layers 24 are fused. |
