Abstract
A waveguide includes a waveguide body which is hollow inside and made from a shape-retentive material, and a conductive inner coating layer which is electrically conductive and provided on an inner surface of the waveguide body. The waveguide uses an inner space of the conductive inner coating layer as a transmission path to transmit electromagnetic waves as signals. Two electric wires provided along the outer surface of the waveguide body serve respectively as a power line and a ground line to transmit electric power.
