The present invention is provided with: an ink storage part for storing ink; a pen tip for applying the ink to an ink application object, the pen tip having a proximal-end part and a distal-end part on the opposite side thereof from the proximal-end part; an ink guiding part for guiding the ink in the ink storage part toward the pen tip; and a holder part having a through-hole through which the pen tip is inserted, the holder part for retaining at least the proximal-end part of the pen tip while exposing the distal-end part of the pen tip in a state in which the pen tip is inserted in the through-hole. The holder part is provided with: an ink retaining part formed in at least a portion of the periphery of the through-hole, the ink retaining part being capable of retaining the ink from the ink guiding part; and a first opening part open on an internal peripheral face demarcating the through-hole, the first opening part being communicated with the ink retaining part.
