PROBLEM TO BE SOLVED: To provide a writing instrument for continuously writing without skip even in the case of a fine lithographic line by increasing a bending resistant strength of an end provided with an expanding slot. SOLUTION: A front end having an expanding slot is bent down toward a front end writing unit to a base end at a nib 5 mounted at a front end of the writing instrument to perform a large bending resistant strength for a writing pressure at the time of writing by the bending to suppress warping of the end of the nib 5 to a nib receiving member 4 and to always maintain the state that a lower surface of the slot of the nib 5 is brought into pressure contact with the end of an ink guide core 6 made of a fiber converging unit. Thus, even in the case of a fine lithographic line, the line can be written without skip. |
