The present invention provides an adhesive composition, an adhesive, an adhesive sheet and an optical film with an adhesive layer that have good durability and good processability when the adhesive composition is applied.nThe solution is an adhesive composition containing (meth)acrylate, which has a molecular weight of 300 in the molecular weight distribution of the (meth)acrylate polymer (A) measured by gel permeation chromatography. The amount of the component of 10,000 or more is 15% by mass or less, and the peak molecular weight (Mp) is 800,000 or more and 1.2 million or less. Then, in a mixed solvent of ethyl acetate and acetone containing 85% by mass of ethyl acetate, make The (meth)acrylate polymer (A) has a viscosity of 5000 mPa when dissolved at a concentration of 20% by mass. Above s, 10000mPa. Adhesive composition below s. |
