发明名称 WRITING INSTRUMENT
摘要 Disclosed is a writing instrument which enables visual identification of a wide range of writing directions through a visual identification section of a pen nib and ensures consistent writing to the last touch of writing. To this end, the pen nib (40) includes a porous structure (45) serving as a writing section, and a holding structure (55) which holds the porous structure (45) and has at least one ink guide section (50) for supplying ink to the writing section. The writing instrument has a relay porous structure (30) for supplying the ink contained in a writing instrument body (10) to the ink guide section (50) provided in the holding structure (55), and allows the holding structure (55) to serve as the visual identification section for visually identifying the direction of writing. The area ratio of the visual identification section to the pen nib (40) that is protruded from the end of the writing instrument body is adapted to be 40% or greater.
