PROBLEM TO BE SOLVED: To provide a liquid spray device capable of reducing variation in the consumption of a spray liquid even if an oscillator deforms in the case of use under the same condition.SOLUTION: A liquid spray device comprises a core material sucking up a spray liquid stored in a storage tank out of the tank, and a support medium supporting a diaphragm atomizing the spray liquid by contacting the core material. The base end side of the diaphragm is supported by the support medium. The core material is contacted to one face of a vibration part protruding from the support medium of the diaphragm, and a pressing body is contacted to the other face, Thereby, the portion of the vibration part positioning at a tip side of the portion contacting with the core material is pressed to the core material side by the pressing body.SELECTED DRAWING: Figure 2
