Abstract: A writing feel improving sheet comprising a base material and a writing feel improving layer with which a touch pen is brought into contact, wherein when a touch pen having a pen tip of 0.5 mm diameter is used to bring the pen tip into contact with a surface of the writing feel improving layer with which the touch pen is brought into contact and the touch pen is then linearly slid at a speed of 1.6 mm/second while applying a load of 200 g to the touch pen and maintaining an angle formed between the touch pen and the surface at 45°, a difference between a maximum value and a minimum value of frictional force generated between the pen tip and the surface is 80 mN or more and 300 mN or less, wherein the frictional force is measured between a point at which a sliding distance is 10 mm and a point at which the sliding distance is 100 mm. The writing feel improving sheet makes it possible to well reproduce the writing feel experienced when writing on paper with a ballpoint pen.
