A pressure-sensitive adhesive composition, comprising:

    a (meth)acryl-based polymer (A); andan ionic compound (B) comprising an anion component and a cation component, whereinthe (meth)acryl-based polymer (A) is a hydroxyl group-containing (meth)acryl-based polymer (A) containing a monomer unit derived from a hydroxyl group-containing monomer, andthe anion component has an organic group and three or more carbon atoms. The anion component is preferably at least one of anion components represented by the following formula (1):(CnF2n+1SO2)2N−  (1)wherein n is an integer of 3 to 10; the following formula (2):CF2(CmF2mSO2)2N−  (2)wherein m is an integer of 2 to 10; and the following formula (3):−O3S(CF2)lSO3−  (3)wherein l is an integer of 3 to 10.
