Abstract
A writing implement of the present invention is capable of stably feeding ink to the tip of a writing member so that the writing member is able to draw lines in a fixed width and in a fixed ink density. The writing member is formed by superposing thin strips so as to form an ink passage of the shape of a minute gap therebetween. The ink is fed to the tip of the writing member by capillarity of the ink passage. Thus, the ink can be always stably fed to the tip of the writing member regardless of changes of the environment.
