A thermal-reaction type flame-retardant pressure-sensitive adhesive tape which has high flame retardancy. It is produced by coating a substrate with a solvent-free photocurable pressure-sensitive adhesive obtained by adding a dripping inhibitor and a flame retardant to a photocurable pressure-sensitive adhesive comprising as major ingredients an alkyl (meth)acrylate monomer, a monomer having a polar group, and a photopolymerization initiator, wherein the dripping inhibitor is a hydroxylated monomer having an optically active functional group and the flame retardant comprises a phosphazene and a hydrated alumina, the amounts of the hydroxylated monomer, phosphazene, and hydrated alumina being 5 to 50 parts by weight, 5 to 100 parts by weight, and 10 to 200 parts by weight, respectively, per 100 parts by weight of the photocurable pressure-sensitive adhesive. |
