PROBLEM TO BE SOLVED: To provide a ball-point pen of a simple structure wherein ink is reserved directly inside a container, by which writing can be carried out over a long period of time by increasing a filled amount of ink, and further continuous ink delivery can be carried out without executing push operation. SOLUTION: A ball point pen 1 is composed of a tip 2, a container 3, and a weight component 8. The tip 2 holds a ball 22 rotatively at a tip opening 21 discharging ink in writing and sucking air according to the discharge of ink. The container 3 reserves ink 9 having shear reduced viscosity inside, and the tip 2 is equipped to a tip so that the tip opening is communicated to an inside. The weight member 8 imparts shearing force to the ink 9 stored, in a transferable manner, in the container 3. |
