Abstract
An element of parallel flat plate line type suitable for operation at a higher speed and with a higher frequency is provided. The element is characterized by including a first metallic memberincluding a flat plate sectionand a projected sectionin which a plurality of projections are formed to stand on one surface of the flat plate sectionin a direction substantially vertical to the surface with gaps therebetween, a second metallic memberincluding a flat plate sectionand a projected sectionin which a plurality of projections are formed to stand on one surface of the flat plate sectionin a direction substantially vertical to the surface with gaps therebetween, and a dielectric filmformed between the projections and the gaps of the element of parallel flat plate line type formed by inserting the projections of the first metallic memberin the gap of the second metallic memberand inserting the projections of the second metallic memberin the gap of the first metallic member, wherein a transmission line is formed between the first metallic memberand the second metallic memberalong the dielectric film, the transmission line being formed to have transmittivity ranging from −140 dB to −20 dB for a high-frequency electromagnetic wave ranging from 100 kHz to 10 GHz supplied from one terminal.
