HIGH FREQUENCY SIGNAL TRANSMISSION LINE, ELECTRONIC APPARATUS, AND METHOD FOR MANUFACTURING HIGH FREQUENCY SIGNAL TRANSMISSION LINE

摘要

Provided are a high frequency signal transmission line, an electronic apparatus, and a method for manufacturing the high frequency signal transmission line which are capable of reducing insertion loss. A dielectric element (12) is formed by laminating layers of a plurality of dielectric sheets (18a-18c). A signal line (20) is provided to the dielectric element (12). In the dielectric element (12), a reference ground conductor (22) is provided further towards one side in the lamination direction than the signal line (20), and opposes the signal line (20). In the dielectric element (12), an auxiliary member (50) is provided further towards the other side in the lamination direction than the signal line (20), and opposes the central section of the signal line (20) in the line width direction. In a cross-section orthogonal to the direction in which the signal line (20) extends, the signal line (20) curves such that both end sections of the signal line (20) in the line width direction are distanced further from the reference ground conductor (22) than the central section of the signal line (20) in the line width direction.
