摘要：
A NRD guide includes a pair of parallel plate conductors opposed to each other at a spacing equal to or shorter than half the wavelength of a high-frequency signal to be transmitted and having opposing inner surfaces whose arithmetic average roughness Ra satisfies 0.1 μm≦Ra≦50 μm, and a dielectric strip arranged between the pair of parallel plate conductors and held in contact with the respective inner surfaces of the parallel plate conductors. The dielectric strip is strongly secured to the inner surfaces to exhibit an excellent durability. The transmission loss of the high-frequency signal can be effectively suppressed.
