PROBLEM TO BE SOLVED: To provide a paste jetting nozzle which can realize a high-quality bonded state at a low paste coverage by spraying paste in a mist state. SOLUTION: This paste jetting nozzle includes: a nozzle body 10 having, in its front end face, a nozzle hole 13 for delivering paste; a cap member 20 mounted on the outer periphery of the nozzle body 10; an air passage 30 having a circular shape in section provided between the nozzle body 10 and the cap member 20; and an air jetting port 32 for jetting air, supplied to the air passage 30, forward from the circumference of the nozzle hole 13 at a given convergent angle. Further, the paste jetting nozzle is constructed so that the pressure of the circumference of the nozzle hole 13 is made negative by the air jetted from the air jetting port 32.
