PURPOSE: A water pen for a computer is provided to prevent the generation of an error upon writing a paper by allowing students taking various kinds of examinations not to need a lot of time upon writing on a computer paper during an examination time and enabling marking on an accurate position. CONSTITUTION: The water pen comprises: a body(110) of a hollow pipe shape; an ink storage portion(120) storing a water ink perceivable by a computer paper reader; a core member(130) draining the ink stored in the ink storage portion(120); and a head member preventing the ink storage portion(120) coupled with the core member(130) from being picked off from the ink storage portion(120). A marking member(150) having the same outer diameter as the inner diameter of a marking portion(210) of a computer paper(200) is formed integrally at the lower end portion of the core member(130) draining the ink stored in the ink storage portion(120). A guide member(140) is installed at an outer lower part of the body(110) with the marking member(150) installed thereto to achieve marking after the marking member(150) is disposed at an accurate position.
