In order to provide a writing instrument applicable to an applicator, in which a writing or applying direction can be visually recognized in a broad range at a visual part of a tip, the writing instrument is endowed with a constitution in which a tip is equipped with a porous member as a writing part and a holding member holding the above porous member and having at least one liquid guiding part for feeding an liquid to the writing or applying part, which comprises a relay porous member for feeding a liquid contained in a instrument main body to the liquid guiding part provided in the holding memberand in which the holding member is a visible part wherein an area ratio of the above visible part on the front or side face is 40% or more of the tip protruding from a tip part.

Writing instrument

In order to provide a writing instrument in which a writing direction can be visually recognized in a broad range at a visual part of a pen tip and which can surely write to end of writing, the writing instrument is endowed with a constitution in which a pen tip is equipped with a porous member as a writing part and a holding member holding the above porous member and having at least one ink guiding part through which an ink contained in a barrel is provided to a writing part held by the holding member which is a visible part enabling to visually recognize a writing direction, wherein an area ratio of the visible part is 40% or more of the pen tip protruding from a tip part of the writing instrument.

To provide a fluid feeder of an applicator having a structure that allows a fluid to flow into a tubular member and be positively pressurized at the time of an ejecting operation, which can readily eject the fluid even if the fluid becomes unlikely to flow out and which allows the user to readily use over a long period of time even if a high-viscosity fluid is used. In the fluid feeder of an applicator, at the time of the closed state, the periphery of a base of a rod-like part comes into hermetic contact with the inner peripheral surface of a fore part of a tubular member. When the thrust against pressing end is weakened after an open state and then the fluid is pressurized before returning to the closed state, the plunger-like part is inserted into the cylinder surface so as to pressurize the fluid held in the space between the inner surface of tubular member and the outer surface on the front side of a step of a valve member, whereby the fluid is flowed out from an ejection opening that is in a state where the periphery of base of valve member is released from the inner peripheral surface of fore part of tubular member.
