PROBLEM TO BE SOLVED: To shorten the curing time while maintaining the length of possible adhesion time after application, preventing the distorted adherend from floating and peeling, and ensuring the adhesion to a less polar adherend, A reactive hot melt adhesive that does not contaminate the work environment is provided. A reactive hot melt adhesive obtained by reacting a polyisocyanate (A), a polyolefin-based polyol (B), and a rosin (C) having an active hydrogen that reacts with an isocyanate is used.
