Abstract:
Provided is a writing implement capable of drawing lines using capillary action, wherein the width of the line can be freely adjusted while the line is being drawn and it is possible to draw lines of almost the same width at the beginning of the use of the writing implement as at the end of use. A felt-tip pen  1  is provided with an ink reservoir  11 , a collector  17 , and a core  29  for drawing by capillary action the ink that has been dispensed by the collector  17 , dispensing the drawn ink from the tip, and adhering same to a paper surface. Even in repetitive writing, the rate of variability in the width of the lines drawn at the end of use with respect to the width of lines drawn at the beginning of use is 10% or less.

Claim (Index 1):
A writing instrument comprising:\n an ink storage part which stores ink; an air replacement mechanism which sends ink from the ink storage part by sending air into the ink storage part; and a central core which sucks the ink sent out by the air replacement mechanism with a capillary force, sends the sucked ink from the tip, and makes the ink adhere to a paper surface, wherein a rate of change is 10% or smaller between widths of lines before writing and after writing at the time when the lines are written alternately and repeatedly with a writing weight of 50 g and a writing weight of 200 g.
