PROBLEM TO BE SOLVED: To provide a transmission line capable of transmitting electromagnetic waves of one or more frequencies within the range of 1-10 GHz in an effective way.SOLUTION: A transmission line of the present invention includes: a line portion with a first relative permittivity, which comprises a first dielectric and a conductor filler dispersed in the first dielectric; and a surrounding dielectric portion which comprises a second dielectric with a second relative permittivity. The surrounding dielectric portion exists around the line portion in a cross section perpendicular to a direction in which electromagnetic waves transmit in the line portion. The relative permittivity of the line portion is 600 or more, and the relative permittivity of the second dielectric is smaller than that of the line portion. Thus, the line portion can transmit electromagnetic waves of one or more frequencies within the range of 1-10 GHz in an effective way.SELECTED DRAWING: Figure 1 |
