The present invention provides an optical member capable of suppressing the occurrence of bending, maintaining high adhesion reliability and transparency, and excellent anti-corrosion effect, and a pressure-sensitive adhesive layer and a pressure-sensitive adhesive sheet capable of efficiently and inexpensively manufacturing such an optical member.
The present invention contains a base polymer and a rust inhibitor, the base polymer does not contain or substantially does not contain an acidic group-containing monomer as a constituent monomer component, and an optical ^{modulus of at least 5.0×10 4 Pa at 85°C.} It provides a pressure-sensitive adhesive layer.
