Abstract
A laminate adhesive includes a curing agent including a polyisocyanate component and a main component including a polyol component, wherein the polyisocyanate component includes an isocyanurate derivative of xylylenediisocyanate, and in the chromatogram when the isocyanurate derivative of xylylenediisocyanate is subjected to gel permeation chromatograph measurement, the area percentage of a peak area having peak top between the polystyrene-based molecular weight of 400 to 1000 relative to the total peak area is 30% or more and 90% or less.
