[PROBLEMS] To bond a protective film to a polarizer and have a sufficiently low viscosity that can be applied at room temperature, exhibiting a sufficient storage elastic modulus after curing, and receiving a severe temperature history However, the present invention provides a photo-curing adhesive that provides a polarizing plate that hardly causes cracking in the polarizer and also has improved adhesion between the polarizer and the protective film. A photocationic polymerization initiator is contained in an amount of 1 to 10 parts by weight with respect to 100 parts by weight of a photocationic curable component, and the photocationic curable component contains the following components. 60 to 75% by weight of alicyclic diepoxy compound, 5 to 35% by weight of diglycidyl compound, and 2 to 15% by weight of monofunctional epoxy compound.
