The present invention relates to a cable tray which reduces the number of components through coupling through an integrated expansion structure and at the same time provides convenience in an assembling operation, and improves a method for coupling between components and at the same time can replace an existing structure, thus providing convenience in production. According to the present invention, provided is a cable tray comprising: first and second side rails (31, 32) which form side walls having a certain width at left and right sides; and a plurality of horizontal bars (33) provided at intervals between the first and second side rails (31, 32), wherein the first and second side rails (31, 32) are formed by coupling between a plurality of side panels (34, 35) via fastening members (36), and expanded end portions (39), into which the end portions of other side panels (34, 35) are inserted, are formed at one end or both ends of the side panels (34, 35). 本发明涉及一种结合一体型扩展结构的电缆桥架，在减少构成要素的同时，为组装作业提供便利，改善构成要素相互之间的
