Abstract:
A writing feel improving sheet having a touch pen contact surface with which a touch pen comes into contact, the writing feel improving sheet having a dynamic friction coefficient as measured when a touch pen is linearly slid on the touch pen contact surface at a predetermined sliding speed, wherein the dynamic friction coefficient when the sliding speed is 1.5 mm/s is 0.13 or more and 0.35 or less, the dynamic friction coefficient when the sliding speed is 20 mm/s is 0.15 or more and 0.40 or less, the dynamic friction coefficient when the sliding speed is 50 mm/s is 0.18 or more and 0.45 or less, and the dynamic friction coefficient when the sliding speed is 80 mm/s is 0.18 or more and 0.47 or less.
