Abstract

A distribution line structure for electric power supply is provided with a pair of first conductors and a second conductor. Each of the first conductors is provided with a first main portion formed in a flat strip shape and first connection portions, and the second conductor is provided with a second main portion formed in a flat strip shape and second connection portions. The first conductors are connected with each other at the first connection portions. The first and second main portions are layered and separated each other by insulators. The second main portion is put between the first main portions.
