To provide a writing utensil formed of a combination of a pen and a correction pen in one piece with such a function that the fixed part, which becomes dry, of a refill in the pen point part of the correction pen can be easily cleaned and restored to its original non-dry state.

An auxiliary housing/incorporating pipe which incorporates the refill of a ball point pen, an aqueous pen or the like is provided in a housing/incorporating pipe for a correction fluid of a correction pen body. This pen can be shortened in overall length by connecting the pen to the correction pen. In addition, the component of the fluid coming into contact with the auxiliary housing/incorporating pipe is uniform by shaking the correction pen. Further, a cleaning chamber with a cleaning rubber or the like fitted to the tip part of a cap which is placed on the part, which becomes dry, of the refill in the pen point part of the correction pen, is provided as a solution of the problem of fluid dryness. Thus the part is restored to its original dryness-free state.
