A ladder for loading and unloading a cargo vehicle according to the present invention comprises: a ladder frame having one side installed on a cargo vehicle and forming an incline with the ground; and an anti-slip plate installed on the ladder frame at a predetermined interval to form an inclined surface; wherein the anti-slip plate is formed by being bent in the longitudinal direction and comprises: raised parts having smooth surfaces; an inlet part formed between the raised parts; and first and second support parts bent downward along the longitudinal direction at both extreme ends. On the smooth surface of each raised part, a friction protrusion part is formed by burring upward from the inner surface. Discharge holes are formed in the inlet part at predetermined intervals. Accordingly, the ladder can help improve productivity.
