In a writing implement having a feeder core for feeding ink in an ink tank to a pen tip and an ink collector in which a plurality of comb-tooth like elements formed with an air-liquid exchange groove are arranged at intervals in a feeder core axial direction, an ink holding plate is provided so as to face a rear end face of the ink collector in such a manner as to form a gap for holding the ink in the ink tank by means of the capillary phenomenon between the ink holding plate and the rear end face, and also a plurality of air exchange grooves for flowing and discharging ink of an amount responding to a change in pressure in the ink tank into and from grooves between the comb-tooth like elements are formed between an outer edge portion of the comb-tooth like element and a feeder core contact portion.
