Capacitive touch panel

A capacitive touch panel, comprising:

• a display device;
• a lower adhesive layer;
• a capacitive touch panel sensor;
• an upper adhesive layer;
• and
• a protective substrate, in this order,
• wherein a maximum value of tan σ of the upper adhesive layer and a maximum value of tan σ of the lower adhesive layer, which are obtained from a temperature dependency evaluation test (Test 1) are 0.08 or less, and also tan σ of the lower adhesive layer at respective temperatures of every 20° C. from −40° C. to 80° C. is tan σ or less of the upper adhesive layer, and
• wherein a maximum value of tan σ of the upper adhesive layer and a maximum value of tan σ of the lower adhesive layer which are obtained from a temperature dependency evaluation test (Test 2) are 0.08 or less, and also tan σ of the lower adhesive layer at respective temperatures of every 20° C. from −40° C. to 80° C. is equal to or less than tan σ of the upper adhesive layer:
• Temperature dependency evaluation test (Test 1):
• an adhesive layer is sandwiched between aluminum electrodes, the temperature increases by 20° C. from −40° C. to 80° C., and tan σ of the adhesive layer is calculated by the impedance measurement at 100 kHz at each temperature, and
• Temperature dependency evaluation test (Test 2):
• an adhesive layer is sandwiched between aluminum electrodes, the temperature increases by 20° C. from −40° C. to 80° C., and tan σ of the adhesive layer is calculated by the impedance measurement at 1 MHz at each temperature.
