<p>Disclosed is an adhesive sheet for optical use that has excellent anti-bleaching properties, excellent adhesive reliability at high temperatures, and excellent level difference absorption. The adhesive sheet for optical use is characterized by: containing an acrylic polymer formed from a monomer-of which the glass transition temperature is at least -10°C when forming a homopolymer-as a required monomer component; having an acrylic adhesive agent layer of which the shear storage modulus is 0.8×105 to 5.0×105 Pa at 23°C; and having a moisture content of at least 0.65 mass% after being stored for 120 hours in a 60°C, 95% RH environment.</p>
