PROBLEM TO BE SOLVED: To comprise a line converter, a high frequency module equipped with the same and a communication device in which plane circuit is located parallel to an electromagnetic wave propagation direction of through a solid waveguide to facilitate working of a dielectric substrate and coupling characteristics of the plane circuit and the solid waveguide configured on the dielectric substrate are prevented from being affected by the assembly accuracy of the both to easily obtain line conversion characteristics as designed. SOLUTION: Ground conductors 4g, 5g, a conductor for a transmission line and a conductor 4k for a coupling line are formed on a dielectric substrate 3, a dielectric charging waveguide is composed of a lower conductor plate 1, an upper conductor plate 2, a lower dielectric strip 6 and an upper dielectric strip 7, the dielectric substrate 3 is held therebetween, such that an attenuation band of the dielectric charging waveguide is composed of a conductor portion S which is a part of the ground conductors on the dielectric substrate. The conductor 14k for the coupling line is coupled at a portion where an electric field strength of a standing wave is highly generated by the attenuation band. COPYRIGHT: (C)2004,JPO
