An applicator comprising: a reservoir for holding therein an application liquid; a valve assembly disposed in a distal region of the reservoir; a tip disposed in front of the valve assembly; the valve assembly comprising: a valve chamber having a forward opening; a valve body held in the chamber and movable fore and aft; and a biasing member for urging the valve body to be pressed against a circular rim around the opening so as to close it, the valve body having a distal portion in contact with a rear end of the tip, wherein the application liquid stored in the reservoir has a viscosity of 100 mPa.s or less, and the applicator further comprises a follower disposed in the reservoir and in rear of a column of the liquid so as to control flow rate of the liquid flowing out through the opening of the valve chamber, with the follower serving also as a back-flow inhibitor for the application liquid, and wherein a viscous material forming the follower shows the value of at highest "2' as the ratio of viscosity at 5° C. to viscosity at 35° C.
