Claims

[Scope of utility model registration request]

An ink absorbing body provided inside the barrel, a pen nib holder provided at the tip of the barrel, and a rear end inserted into the ink absorbing body so as to have open air bubbles and generate a capillary phenomenon. an ink introduction core whose front end protrudes from the nib holder; and a pen nib whose tip protrudes from the nib holder and is fixed between an inner periphery of the nib holder and an outer periphery of the ink introduction wick. In the writing instrument equipped with the above, the cross-sectional outer shape of the ink introduction core in the nib holder portion is approximately equal to the cross-sectional inner shape of the nib holder, and the ink introduction core is attached to the nib holder. A fountain pen-shaped disposable writing instrument characterized by being supported in a tilted manner.
