Abstract
A (meth)acrylic copolymer (A) having a mass average molecular weight of 50,000 to 1,000,000, in which the (meth)acrylic copolymer (A) is obtained by polymerizing a monomer mixture including a macromonomer (a) that has a number average molecular weight of 500 or more and less than 6000 and a vinyl monomer (b), and preferably includes 7 to 40% by mass of a repeat unit derived from the macromonomer (a), has sufficient coating workability, adhesive holding power and adhesive property as an adhesive composition.
