TRANSMISSION LINE, AND METHOD FOR MANUFACTURING TRANSMISSION LINE

WIPO Patent Application WO/2024/009856

A1

The present invention provides a transmission line (20) that has shielding performance, is thin, and has a structure with low transmission loss. The transmission line (20) comprises: a first conductor (31) consisting of a transmission line conductor (32) and a ground conductor (33); a first base (34) on which the first conductor (31) is formed; a coverlay (35) that covers the transmission line conductor (32); a first shield (40) in which a second conductor (41) is formed on a second base (42); and a second shield (45) in which a third conductor (46) is formed on a third base (47). The coverlay (35) is thermocompression bonded to the first base (34), the first base (34) is thermocompression bonded to the second base (42), and the third base (47) is thermocompression bonded to the coverlay (35). The second conductor (41) and the third conductor (46) are arranged to surround the transmission line conductor (32) and are ultrasonically joined to each other, and in the second conductor (41), a folded-back end part (41a) is overlapped and ultrasonically joined to the ground conductor (33).
