PROBLEM TO BE SOLVED: To provide a liquid dripping device capable of dripping a liquid such as liquified solder to an object in an accurate minute amount.SOLUTION: A guiding cylindrical part for storing a liquid for dripping and having a cylindrical inner shape in a liquid reservoir communicating with a nozzle hole is arranged. A columnar reduced-diameter end part, which is coaxial with the guiding cylindrical part, is arranged at a tip of a rod drivable in a linear manner in an opening direction of the nozzle hole. Compressional waves travelling in a liquid dripping direction are generated in a stored liquid by making the reduced-diameter end part drive in a linear manner inside the guiding cylindrical part, and a predetermined amount of liquid is dripped from the nozzle hole by utilizing wave energy which the compressional waves have. |
