  Provided are a writing instrument produced at a lower cost than conventional thermochromic writing instruments utilizing frictional heat, slim like a pencil and not bulky because it contains an ink directly in a barrel thereof, and excellent in portability; and a set of the writing instruments. The writing instrument 1 is obtained by directly filling a barrel thereof with an ink 2 which becomes colorless or colored, or undergoes a color change by heating and an ink follower 5 following the ink with its consumption; firmly fixing a writing tip portion 3 to the end of the barrel directly or via a relay member; and disposing a friction body 6 having an elasticity at the rear end portion of the barrel. The writing instrument set has a plurality of the writing instruments respectively different from each other in color tone.

  本发明提供了一种书写工具，与传统的利用摩擦热的热致变色书写工具相比，其生产成本更低；该书写工具像铅笔一样纤细，由于直接在其笔管中装有墨水而不笨重，并且便携性极佳；还提供了一套该书写工具。 书写工具 1 是通过以下方式获得的：在其笔管中直接注入墨水 2，墨水 2 通过加热变为无色或有色，或发生颜色变化，墨水跟随器 5 随着墨水的消耗而变化；将书写尖端部分 3 直接或通过中继部件牢固地固定在笔管的末端；以及在笔管的后端部分配置具有弹性的摩擦体 6。这套书写工具具有多个色调各不相同的书写工具。
