Abstract
A writing implement having a cap member is provided and is a direct-flow type (liquid ink type) writing implement including: a barrel cylinder; a holder holding a pen core at a front end of the barrel cylinder and further having inside the barrel cylinder, an ink tank for storing a liquid ink and a collector for temporary retention thereof. The collector, barrel cylinder and ink tank are formed of a clear, transparent material. A mouthpiece at the outer periphery of the holder is formed of a resin material having the same color as the ink held in the ink tank or having the same color as the written ink. The barrel cylinder may have a partition wall, positioned near to the center, on the side (rear side) opposite to the position where the collector is arranged, forming an ink tank in a space inside the barrel between the rear end plate of the collector and the partition wall.
