PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive composition and a pressure sensitive adhesive sheet-like formed body having adhesive strength, transparency, flexibility and tensile strength with good balance, a method of manufacturing them, and a display unit including the pressure sensitive adhesive composition or the pressure sensitive adhesive sheet-like formed body.SOLUTION: In a mixed composition of 100 pts.mass of a (meth)acrylic resin composition (A) including not less than 5 mass% and not greater than 25 mass% of a (meth)acrylic acid ester polymer (A1) having a weight average molecular weight (Mw) of greater than 300,000 and not greater than 2,000,000, not less than 10 mass% and not greater than 95 mass% of a (meth)acrylic acid ester polymer (A2) having a weight average molecular weight (Mw) of not less than 5,000 and not greater than 300,000, and not less than 0 mass% and not greater than 85 mass% of a (meth)acrylic acid ester monomer (α1), and not less than 0.05 pts.mass and not greater than 8 pts.mass of a polyfunctional epoxy compound (B) having not less than 2 and not greater than 10,000 functional groups, at least polymerization reaction of the (meth)acrylic acid ester monomer (α1) and crosslinking reaction of the (meth)acrylic acid ester polymer (A1), the (meth)acrylic acid ester polymer (A2), or a polymer having a structural unit derived from the (meth)acrylic acid ester monomer (α1) are taken place. |
