PURPOSE: Writing instruments are provided to reduce loss of ink by moving leaked ink to a core body through a leaking-ink passage, and to completely use the ink which is stored in an ink tank by directly connecting the ink tank with the core body. CONSTITUTION: Writing instruments include the following: a tank holder(300) with a core hole(310), a cylindrical container part(320), and a leakage ink passage(350); a first leak ink path(600) formed by inserting a core fixing part(410) into the container part of the tank holder; a core-body holder(400) with a container part forming a second and a third leakage ink passage; an ink supply part(150) formed between a holder and the container part; and a support cap part(500) supporting a core body(100). |
