Patent number: 10580548Abstract: A carbon nanotube composite material (1) includes a metal base material (10) and carbon nanotube electrically-conductive path portions (20). The metal base material (10) is made from a polycrystalline substance in which a plurality of rod-shaped metal crystal grains (11) are oriented in a direction. The carbon nanotube electrically-conductive path portions (20) are made from doped carbon nanotubes having a dopant, existing in parts of grain boundaries (15) between the rod-shaped metal crystal grains (11) in a cross section of the metal base material (10), and forming an electrically-conductive path which is electrically conductive in a longitudinal direction of the metal base material (10), by existing along the longitudinal direction (L).Type: GrantFiled: November 22, 2016Date of Patent: March 3, 2020Assignees: YAZAKI CORPORATION, The University of TokyoInventors: Ken Nishiura, Junichiro Tokutomi, Hideo Gonda, Jun Yanagimoto
