Abstract

L'invention concerne un câble capable de supprimer la désadaptation d'impédance provoquée par la flexion et la torsion, tout en diminuant la constante diélectrique entre le conducteur interne et le conducteur externe. Un câble coaxial (1) est pourvu d'un conducteur interne (10), d'un élément isolant (20) couvrant la circonférence externe du conducteur interne (10), et d'un conducteur externe (30) couvrant la circonférence externe de l'élément isolant (20). L'élément isolant (20) est caractérisé en ce qu'il présente une tresse en résine (21) tissée à partir de fibres de résine isolantes multiples (22). Grâce à une telle configuration, des espaces sont formés entre les fibres de résine voisines (22) et entre le conducteur interne (10) et les fibres de résine (22), ce qui permet de diminuer la constante diélectrique entre le conducteur interne (10) et le conducteur externe (30). En outre, étant donné que la variation des positions relatives des fibres de résine (22) et la variation de la taille des espaces entre les fibres de résine (22) peuvent être supprimées, la fluctuation de la constante diélectrique entre le conducteur interne (10) et le conducteur externe (30), et la désadaptation d'impédance dans le câble coaxial (1), peuvent également être supprimées.
