Provided is a pressure-sensitive adhesive sheet which exhibits high durability when various film members are used as adherends and has excellent lamination properties, and an optical laminate obtained by using the pressure-sensitive adhesive sheet. The pressure-sensitive adhesive sheet has at least a pressure-sensitive adhesive layer, the pressure-sensitive adhesive layer containing light-diffusing fine particles, and a storage elastic modulus of the pressure-sensitive adhesive layer at 23 ° C. of 0.1 MPa or more and 1.0 MPa or more. For the pressure-sensitive adhesive layer 11, the total value of the image clarity of the optical combs of 0.125 mm, 0.25 mm, 0.5 mm, 1.0 mm, and 2.0 mm measured according to JIS K7374: 2007 is as follows. , 250% or more and 480% or less, the haze value of the pressure-sensitive adhesive layer 11 is 20% or more and 80% or less, and the adhesive force of the pressure-sensitive adhesive sheet 1 to the polyethylene naphthalate film is 3.0 N / 25 mm or more.
