PROBLEM TO BE SOLVED: To provide a double jetting head capable of distributing a pesticide or the like jetted from both left and right jetting ports of a double passage part uniformly in the back and forth direction, hardly generating the fluctuation of spreading density, hardly suffering the wear, the deformation, the damage or the like in the double passage part, capable of improving strength and durability and having simple structure to enable to decrease the production cost. SOLUTION: The double jetting head has an engaging passage part (11) connected to a connection pipes (20) such as straight pipes, bent pipes, a single cylindrical passage (12) successively provided in the downstream side of the engaging passage part (11) and the double passage part (13) branched into both left and right ways to draw a hyperbola or a bicircular arc and a collar part (15) is projectingly provided forward from the center part of the front side part of the double passage part (13) in the upper and lower direction.
