Conductor for electric circuit

The present invention discloses a conductor 1 for electric circuit. The electric circuit is provided with a plurality of conductors 1 spaced apart from each other at intervals along a traveling path of a traveling body, so as to allow a collector to be slidably connected to the conductor 1 and simultaneously move the traveling body for collecting power from the conductor. The conductor has a sliding surface 11 slidably connected to the collector, a neighboring surface 12 neighboring to the sliding surface 11, and a plurality of cut-in parts 13 formed in the boundary between the sliding surface 11 and the neighboring surface 12 at a specific distance L along the traveling direction of the traveling body. The specific distance L of the plurality of cut-in parts 13 is smaller than half of the value obtained by reducing a specific insulating distance L2 from the specific neighboring distance.
