A writing stem for writing instruments which can give an appropriate cushion effect to the griping thumb and fingers includes a grip section formed of an elastic material. A plurality of protruding pieces that can be bent by the gripping force are formed in parallel to one another on the surface of the grip section, including a portion about 30 mm to about 40 mm behind the tip of the writing instrument, and this plurality of protruding pieces are formed over a length equivalent to about ⅔ of the overall length of the grip section in the longitudinal direction.
