ABSTRACT:
A roll-point pen in which a roll having an ellipsoidal portion is held rotatably, around the longer axis thereof as a center, to a tip of a pen holder having an ink reservoir. A plurality of ridges are formed, each being oblique to the longer axis of the ellipsoidal portion, so that a rotational force is provided to the roll due to friction between it and the surface of a paper sheet when the roll is drawn in the direction of the longer axis thereof.
