PROBLEM TO BE SOLVED: To provide a mixing module for a spray gun for operating in a stable state for a long time with satisfactory mixing performance of material having high reactivity and high viscosity. SOLUTION: In the mixing module 1 for two-liquid collisional mixture type spray gun, directions of two or more inlet holes 14a, 14b for introducing two liquids into a mixing chamber 11 are set reversely to a discharging direction of mixture liquid from the chamber and to a range of an angleθof 45 to 85 degrees to a plane Po including a central axis O of the chamber and perpendicular to planes P1 , P2 including central axes of the holes, and openings of the holes to the chamber are disposed on the same circumference in the plane perpendicular to the axis O of the chamber.
