A collector type writing implement, comprising a compartment part approximately dividing an ink tank into two parts, a snorkel having a tubular ventilating part allowing spaces at the front and rear of the compartment part to communicate with each other, and an ink inducing part of a size smaller than that of the ventilating part provided in the compartment part at least at one position, wherein a space part allowing ink and air bubbles to be moved is provided between the collector and the snorkel, parts ranging from the compartment part to the rear end of the collector are formed so that ink spreads over the surfaces of those parts other than the ink tank, the end part of a tubular ventilating part of the snorkel is notched to increase an opening area for effectiveness, and the implement is formed so as to meet the requirements of both expressions Ts>Is and Tt>It where the comprehensive minimum cross-section of the ventilating part is Ts, total distance of the ventilating part is Tt, comprehensive minimum cross-section of the ink inducing part is Is, and total distance of the ink inducing part is It.
