Abstract: A weight can be reduced, and a desired bent shape can be easily obtained with the shielded pipe of the present application. An electric wire that connects a battery and an inverter is inserted into a shielded pipe arranged underneath a floor of a vehicle. The shielded pipe has a pipe body that is made of a synthetic resin material and shaped into a predetermined shape. After the pipe body is shaped, a shielding portion is formed by spirally winding a ribbon-shaped metal foil around the outer circumferential surface of the pipe body. Furthermore, the shielding portion is inserted into a heat-shrinkable tube. The heat-shrinkable tube is heated and covers the outer circumferential surface of the shielding portion in a tight contact state, thus constituting a protective portion for protecting the shielding portion.
