Abstract
A pressure-sensitive adhesive composition according to an embodiment includes: 100 parts by mass of a polymer (A) having a glass transition temperature lower than 0° C.; and 0.1 to 20 parts by mass of a polymer (B) that contains, as monomer units, both a monomer having a functional group equivalent (Fge) of 1000 g/mol≤Fge<15000 g/mol and having a polyorganosiloxane skeleton and a monomer whose homopolymer has a glass transition temperature of 40° C. or higher, and that has a weight average molecular weight (MwB) of 10000≤MwB≤100000.
