は38mmのものが採用されている。The ultrasonic transmitter 2 forms a spray head 7 having a structure capable of withstanding strong vibrations. The head material is titanium alloy, stainless steel, or the like. Further, the width thereof has a dimension of 30 to 120 mm and is determined by the viscosity of each liquid. For example, for a low viscosity liquid of 3 to 7 cst such as water or an aqueous solution, a spray head having a width of 38 mm is used.
