摘要：PROBLEM TO BE SOLVED: To provide a telescopic ladder having a greater maximum reach.SOLUTION: A telescopic ladder (10) has a proximal side end (12) that is configured to be fixed to a substrate. A plurality of ladder parts (18) capable of being mutually displaced to extend the ladder (10) are provided between the proximal side end (12) and a distal side end (16). Specific gravity of a material constituting the ladder part (18) arranged in a position of the proximal side end (12) of the ladder (10) is greater than that of a material forming at least one of the other ladder parts (18) of the ladder (10).SELECTED DRAWING: Figure 1
