PROBLEM TO BE SOLVED: To provide a radiation-curable composition for adhesive having excellent coating property and allowing manufacture of a polarizing plate having heat and humidity resistance, excellent in adhesive strength (peeling strength) or the like in a simple manufacturing step for a short time and the polarizing plate formed using the composition. SOLUTION: The radiation-curable composition for adhesive contains (A) an alicyclic epoxy compound, (B) a compound having number-average molecular weight of≥400 expressed in terms of polystyrene measured by gel permeation chromatography and having≥2 hydroxy groups, (C) a compound having≤10 mPa s viscosity at 25°C and having one hydroxy group and (D) a photo-acid-generating agent. The polarizing plate 1 is formed by laminating protective films 5, 6 across adhesive layers 3, 4 comprising a cured material of the radiation-curable composition for the adhesive on both surfaces of a polyvinyl alcohol-based polarizing film 2.
