PROBLEM TO BE SOLVED: To provide a ball-point pen which has a barrel formed of a conventionally used material, instead of a specific material and further, has such advantages that the forcing part of a tip holder is forced to prevent the tip holder from easily coming off, the tip part of the barrel hardly develops cracks and shear-thinning ink is directly packed in the barrel. SOLUTION: The ball-point pen is of such a construction that the tip holder having a fitted ball-point pen tip with a ball housed, in a freely rotating manner, in the tip is mounted by forcing the forcing part into the tip part of the barrel in which the shear-thinning ink and a grease-like follower to follow in accordance with the ink consumption are directly packed, the follower being positioned after the ink. In this ball-point pen, the forcing part of the tip holder is extended in the axial direction and the rear end of the forcing part is positioned at the rear end beyond the gripping part. |
