PROBLEM TO BE SOLVED: To provide an optical adhesive sheet capable of suppressing changes in the electrostatic capacity causing malfunction when applied to optical members.SOLUTION: The optical adhesive sheet contains an adhesive agent layer, and has a relative permittivity of 2 to 8 at a frequency of 1 MHz, and a dielectric tangent of >0 and ≤0.2 at a frequency of 1 MHz. In the optical adhesive sheet, the relative permittivity at a frequency of 1.0×10Hz is preferably 60% of that at a frequency of 1.0×10Hz. The absolute value of a difference in dielectric tangent is preferably ≤0.15 between at a frequency of 1.0×10Hz and at a frequency of 1.0×10Hz. |
