In the application instrument provided in accordance with the present invention, an operating member inserted in the middle cylinder so as to be movable backward and forward in the axial direction thereof is operated so that a valve mechanism provided in the front portion of the middle cylinder is operated to supply the penpoint with the applied liquid stored in the rear portion of the middle cylinder. The valve mechanism includes a valve seat having a valve hole, a valve spindle provided with a valve element for opening and closing the valve hole, and a stretchable member for moving the valve spindle backward and forward. The stretchable member is elongated and shortened in the axial direction of the middle cylinder as the bent portions of the bent arms are bent less and more, respectively. The operating member is disposed behind the valve mechanism. An operating element provided at the rear end of the middle cylinder is operated to move the operating member forward to push the bent portions of the bent arms to elongate the stretchable member so that the valve spindle is moved backward to open the valve hole to supply the applied liquid to the penpoint.
