摘要:
Provided is an adhesive containing an isocyanate group-terminated prepolymer. The isocyanate group-terminated prepolymer contains a reaction product of a polyisocyanate component containing xylylene diisocyanate and a polyol component containing a polyester polyol and a low molecular weight diol. The isocyanate group-terminated prepolymer has a skeleton represented by a structural formula (A). The content ratio of the skeleton represented by the structural formula (A) is 40% by mass or more relative to the total amount of the isocyanate group-terminated prepolymer.
