Abstract
A capacitance touch panel includes a display, a lower adhesive layer, a capacitance touch panel sensor, an upper adhesive layer, and a protective substrate, which are formed in this order. A temperature dependency of relative permittivity in the upper adhesive layer and a temperature dependency of relative permittivity in the lower adhesive layer as determined by a temperature dependency evaluation test are both up to 30%.
