Patent number: 12120860Abstract: The present disclosure is directed to achieve greater space efficiency. A wiring module (A) includes a first transmission line (20), and a noise shielding member (40) that has a sheet shape and is arranged along the first transmission line (20). The noise shielding member (40) has a thickness of 100 ?m to 600 ?m. Since the noise shielding member (40) has a sheet shape, and thus the space for arranging the noise shielding member (40) can be made smaller, it is possible to achieve greater space efficiency. Since the noise shielding member (40) has a thickness of 100 ?m to 600 ?m, it is possible to obtain a high noise shielding effect.Type: GrantFiled: February 26, 2021Date of Patent: October 15, 2024Assignees: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Hiroyuki Kodama, Kiyoshi Kato, Yuya Iwaguchi, Shuhei Ozu
