Provided is a two-component curing adhesive using a curing reaction of a polyisocyanate composition (X) and a polyol composition (Y), wherein the polyisocyanate composition (X) contains a polyisocyanate (A) and the polyol composition (Y) contains polyol (B). The extensional viscosity of the polyol composition (Y) is 0.1 Pa.s or less. L'invention concerne un adhésif de durcissement à deux composants utilisant une réaction de durcissement d'une composition de polyisocyanate (X) et une composition de polyol (Y), la composition de polyisocyanate (X) contenant un polyisocyanate (A) et la composition de polyol (Y) contenant du polyol (B). La viscosité extensionnelle de la composition de polyol (Y) est de 0,1 Pa.s ou moins. ポリイソシアネート組成物（Ｘ）とポリオール組成物（Ｙ）との硬化反応を用いる二液硬化型接着剤であって、前記ポリイソシアネート組成物（Ｘ）がポリイソシアネート（Ａ）を含み、前記ポリオール組成物（Ｙ）がポリオール（Ｂ）を含み、かつ前記ポリオール組成物（Ｙ）の伸長粘度が１Ｐａ・ｓ以下である、二液硬化型接着剤とする。
