PURPOSE: A keyboard cover is provided to facilitate a blood circulation of a user by forming semispherical pressure protrusions on an upper surface as well as to prevent dust or abnormal material from being heaped up over the keyboard. CONSTITUTION: The keyboard cover(20) includes a plurality of semispherical pressure protrusions(30). The keyboard cover(20) prevents dust or abnormal material from being accumulated on the keyboard. The semispherical pressure protrusions are formed on the upper surface of the keyboard cover(20). Every time the user pushes keys for inputting data, the protrusions, formed equidistantly, presses the fingers of the user. The pressure on the fingers facilitates a blood circulation, then has a healthful effect on the endocrine system via the autonomic nervous system, and metabolizes the physical body.
