A textured surface satisfying all of the following conditions ‘a’ to ‘d’ is provided on the operating surface side of the electrostatic capacitance type touch panel (4). Condition ‘a’: Ra (arithmetic mean roughness) of 0.1-0.5 μm. Condition ‘b’: RΔq (root-mean-square gradient) of 2° or greater. Condition ‘c’: Rsm (mean spacing between profile peaks) of 0.1 mm or less. Condition ‘d’: Rp (maximum peak height) of 1.0 μm or less. All of these values are measured in accordance with JIS B0601:2001.
