PROBLEM TO BE SOLVED: To provide a radiation curable hot melt pressure-sensitive adhesive having a long pot life and excellent handleability and capable of easily visually recognizing gelation. The radiation-curable hot melt pressure-sensitive adhesive of the present invention has 100 parts by weight of an acrylic polymer having a radiation reactive group, 3 to 20 parts by weight of an acrylic monomer, and a structure represented by the formula (1). Since it contains 0.002 to 0.2 parts by weight of a polymerization inhibitor, the pot life is long and the handleability is excellent, and even if gelation occurs unexpectedly, the color It can be easily recognized by changing the value, and it is possible to quickly cope with gelation.
