摘要： A writing implement includes a cylindrical shaft member, a pen tip member which is fixed to one end of the shaft member and from which colored ink seeps out, liquid for ink which is stored in the shaft member and which comprises a part of the colored ink seeping out from the end of the pen tip member, and colorant to be added to the above described liquid for ink to be the colored ink. Moreover, at least a part of a cylindrical side surface of the shaft member corresponding to the storing part of the liquid for ink is formed to be transparent. Between the liquid for ink and the colorant-storing part storing the colorant is provided a colorant-adsorbing core which introduces the liquid for ink into the colorant-storing part while capturing the colorant diffusing toward the storing part of the liquid for ink.

摘要： A writing implement includes a cylindrical shaft member, a pen tip member which is fixed to one end of the shaft member and from which colored ink seeps out, liquid for ink which is stored in the shaft member and which comprises a major component of the colored ink seeping out from an end of the pen tip member, colorant to be added to the liquid for ink, and a valve member for isolating the colorant from the liquid for ink. In the writing implement, at least a part of a cylindrical side surface of the shaft member corresponding to a part where the liquid for ink is stored is formed to be transparent, the valve member is positioned between the storing part of the liquid for ink and the colorant, and the storing part of the liquid for ink is provided with a pressure-regulating part.
