Abstract: Provided is an ink follower which has stable followability regardless of a pen body specification, a flow rate for writing and a writing speed and does not cause back leaking of the ink originating in shortage in the ink follower in the middle of writing and scattering of the ink follower by impact applied to the pen body and which does not flow out from the ink reservoir in storing the pen body at a high temperature and provides a stable flow rate for writing. Further, provided is an ink follower which prevents the ink from volatilizing by shutting off the ink from the outside air (volatilization preventing property) and which prevents the ink from leaking in writing with the pen turned upward. The above ink follower includes, for example, an ink follower characterized by containing a non-volatile or slightly volatile organic solvent and a non-styrene base thermoplastic elastomer which is soluble or swollen in the organic solvent and showing viscoelasticity which is predominant in elastic response.
