A pressure-sensitive adhesive composition includes: 100 parts by mass of a polymer (A) having a glass transition temperature lower than 0° C.; and 0.05 parts by mass to 20 parts by mass of a (meth)acrylic polymer (B) having a weight average molecular weight (MwB) of 1000≦MwB<30000 that contains, as monomer units, both a (meth)acrylic monomer having an alicyclic structure represented by the following general formula (1) and a monomer having a polyoxyalkylene skeleton: n CH 2 ═C(R 1 )COOR 2 (1)n n [wherein R 1 represents a hydrogen atom or a methyl group and R 2 represents an alicyclic hydrocarbon group having an alicyclic structure.] |
