Abstract
Provided is a pen input device sheet disposed over a position detection region of a position detecting sensor, the pen input device sheet including an elastic material layer that is composed of a plurality of layer portions stacked in a thickness direction and has elasticity, an opposite side of a side of the position detecting sensor in the elastic material layer being employed as a side of a writing input surface to which writing input with an electronic pen is made, and the pen input device sheet being configured such that a vibration frequency characteristic of a kinetic friction coefficient when the electronic pen is moved at a predetermined speed on the writing input surface of the pen input device sheet matches a vibration frequency characteristic of a kinetic friction coefficient when a predetermined writing material is moved at the predetermined speed on a predetermined writing medium.
