Abstract

Provided is a two-component curable adhesive using a polyurethane polyisocyanate in which side reactions are suppressed during urethanization reaction and at the time when an unreacted isocyanate monomer content is removed by distillation. This two-component curable adhesive contains a polyisocyanate composition (X) and a polyol composition (Y), in which the polyisocyanate composition (X) contains a polyurethane polyisocyanate (Al), a diisocyanate monomer (A2), and a polyphosphoric acid (B), a content of the diisocyanate monomer (A2) occupying the polyisocyanate composition (X) is 0.1 mass% or less, and a proportion of the polyphosphoric acid (B) to the polyurethane polyisocyanate (Al) is 100 ppm or more and 5,000 ppm or less.
