PCT No. PCT/JP96/02307 Sec. 371 Date Apr. 24, 1997 Sec. 102(e) Date Apr. 24, 1997 PCT Filed Aug. 16, 1996 PCT Pub. No. WO97/07989 PCT Pub. Date Mar. 6, 1997An ink passage (6) including a shallow groove (6a) having the shape of a thin film and forming a very small gap capable of exercising capillarity and deep grooves (6b) of a depth greater than that of the shallow groove (6a), is formed in a joining surface (5) of a pen nib formed by putting a pair of nib elements (1a, 1b) together in a face-to-face disposition and by fixing rear portions of the nib elements to a neck tube (2) or the like of a pen barrel. Front portions, i.e., nonfixed portions, of the pair of nib elements (1a, 1b) are formed in elastically deformable shapes so that the front portions are able to slide relative to each other when writing force is applied to the tip of the nib. The pen nib is capable of giving a writing touch similar to that given by a fountain pen provided with a metal nib, of supplying a sufficient quantity of ink to the tip thereof, of writing "smoothly" under low writing force both when moved "slowly" and when moved "quickly" and of giving a weak feeling of the resistance of the paper sheet. The nib rarely suffers from insufficient flow of ink due to dry residues of ink accumulated in the ink passage.
