An elbow supporter for a computer mouse and keyboard includes a clamp for clamping the supporter on a table of a computer, a threaded rod combined with the clamp and further with a connecter threadably engaging the threaded rod, a first pivotal arm pivotally connected to the connecter at a first end, a first end of a second pivotal arm pivotally connected to a second end of the first pivotal arm. An elbow support disc is fixed on a second end of the second pivotal arm so the elbow support disc may be lifted or lowered by rotating the second threaded rod clockwise or counterclockwise. A mouse sheet is fixed on and moved together with the first pivotal arm, so the mouse sheet may also move up or down together with the elbow support disc.
