PROBLEM TO BE SOLVED: To provide an adhesive composition, an adhesive and an adhesive sheet having antistatic property and showing excellent stress relief property and durability when applied to an optical member such as a polarizing plate.SOLUTION: The adhesive composition comprises a first (meth)acrylate polymer (A) having a weight average molecular weight of 500000 to 3000000, a second (meth)acrylate polymer (B) having a weight average molecular weight of 8000 to 300000, a crosslinking agent (C), and an antistatic (D). The ratio of (B) to 100 parts by mass of (A) is 5 to 50 parts by mass; and (B) contains a monomer having a functional group (b1) reactive with the crosslinking agent (C), in which the ratio of the monomer having (b1) is 5 to 50 mass% in (B). The polymer (A) does not contain a monomer having a functional group reactive with the crosslinking agent (C), or contains a monomer, as a constituent, having a functional group (a1) with lower reactivity with the crosslinking agent (C) compared to (b1). |
