Provided is a writing implement that maximizes the effective area of a viewer portion allowing visual recognition in the writing direction and that facilitates writing at a high level, at the same time. This writing implement is a writing implement A, including for example, a pen tip 20 that feeds ink from a writing implement body 10 and has a viewer portion 33 allowing visual recognition in the writing direction. The pen tip 20 is comprised of, at least, a writing part 25 and a retainer 30 having the viewer portion 33, an ink feeder portion 26 for feeding the ink from the writing implement body 10 to the writing part 25. The minimum width X of the viewer portion 33 is 3.7 mm or greater and a length Y of the viewer portion 33 is 7.4 mm or greater. The ink feeder portion 26 is arranged on one side of the viewer portion 33. Specifically, the ink feeder portion 26 is preferably adapted to be positioned on a near side during writing (on such a side that the pen tip 20 is located on an obtuse angle side of the ink feeder portion 26).
