PROBLEM TO BE SOLVED: To seduce the suction of dust and thereby prevent a gripping member from fouling by forming the gripping member formed in rubber or a thermoplastic elastomer in a gripping part, of the material kneaded with an antistatic resin. SOLUTION: The transparent barrel body 2 of a knocking-type ball-point pen barrel 1 is formed of an acrylonitrile/styrene resin (AS resin). Next the gripping part 3 of the barrel body 2 is formed to be of a small outside dia. and the yellow gripping member 4 of the gripping part 3 is formed in two colors. The gripping member 4 is formed in two colors using a material obtained by adding 20 wt.% pelletized antistatic resin to a thermoplastic elastomer of an olefin resin. In addition, a recessed groove 6 formed in the shape of a ring for antiskid is provided on the surface 5 of the gripping member 4. The gripping member 4 has the effect to attenuate static electricity charged to the gripping member 4 as it is made of the material kneaded with the antistatic resin. |
