PURPOSE: A cable tray is provided to be easy to fabricate and carry by making the construction of the cable tray, guiding a cable up to a desired destination, become light weight. CONSTITUTION: A cable tray comprises a plurality of support iron cores(23) in which a cable(40) is disposed and which are stood in a predetermined interval. The support iron cores(23) are bent so as to have an U-shape, respectively. Upper connection iron cores(21,21') are installed at upper parts of the support iron cores(23) by a spot welding so as to connect the upper parts of the support iron cores(23). Middle connection iron cores(22,22') are installed at middle parts of the support iron cores(23) by a spot welding so as to connect the middle parts of the support iron cores(23). The upper and middle connection iron cores(21,21',22,22') are welded at outer sides of the support iron cores(23) so as not to infringe an inner space formed by the support iron cores(23).
