FLEXIBLE WAVE GUIDE, MANUFACTURING METHOD OF THE FLEXIBLE WAVE GUIDE, AND VIDEO IMAGE TRANSMISSION DEVICE USING THE FLEXIBLE WAVE GUIDE

摘要

To provide a flexible wave guide distributing an extrusion molding of a polar resin in an outer area by arranging a crystal powder in an inner side area of an inner dielectric body.SOLUTION: A flexible wave guide comprises: a dielectric body having a liner flexibility in which a dielectric ratio is uniformity in a longitudinal direction, and a cross section makes the same shape in the longitudinal direction; and an outer conductor 53 distributed at a position covering an outer periphery of the dielectric body, and formed in a cylinder shape having the flexibility. The dielectric body includes: a second dielectric body 52 having a tube-shaped space continued as a center in the longitudinal direction; and a first dielectric body 51 distributed in the tube-shaped space to be held by the second dielectric body 52. The second dielectric body 52 is formed by a resin porous body having a continuous air hole, and the first dielectric body 51 is a collector body of the crystal powder, and having the size of the resin porous body according to the second dielectric body 52 which is larger than that of the continuous air hole.SELECTED DRAWING: Figure 1
