To provide an electric path that facilitates preceding cable laying during block turnover of a vessel, reduces friction between cables and the electric path when drawing in the cables, reduces working time for cable laying, and is utilized for cable laying eliminating the need for cable arranging work during block normal rotation.

A double-sided tray electric path is a vessel's cable laying electric path with a prescribed rectangular shape and a cross-sectional H shape that has side plates on both sides in the width direction. The electric path is provided with a plurality of cable lashing hole rows each of which is composed of a plurality of rectangular cable lashing holes with a prescribed length and a prescribed width per row. Each cable lashing protrusion is provided on both sides of each cable lashing hole row near the cable lashing hole rows. Each cable lashing protrusion maintains a prescribed gap between the electric path and cables when lashing the cables with each cable lashing belt. The cable lashing hole rows are alternately provided on both faces of the upper face and the lower face of the electric path.
