An adhesive, which is a water-based adhesive for paper straws containing ethylene-vinyl alcohol copolymer (A) and water, wherein the ethylene unit content of the ethylene-vinyl alcohol copolymer (A) is 1 mol% or more and less than 20 mol%, the block character of the ethylene unit is 0.90～0.99. The water-based adhesive contains an ethylene-vinyl alcohol copolymer (A) with a specific structure, and has excellent high-speed coatability, film strength, initial adhesion, dynamic water resistance, and acid resistance. It has an excellent balance of high-speed coatability, film strength, and The acid resistance is particularly excellent. |
