In an ultrasonic atomizing cultivation apparatus including a mist supply pipe having an ejection hole for supplying an atomized nutrient solution to a root portion of a plant, an ejection hole is formed by a mist that has been condensed into water droplets. An ultrasonic atomizing cultivation apparatus that prevents clogging is provided. An ultrasonic atomizing cultivation apparatus includes a hollow cultivation tube 101 in which an upper surface is configured by a panel 121 that holds a seedling of a plant 106 and a root portion 125 of the plant 106 hangs down, and an inside of the cultivation tube 106. A spray hole 124 corresponding to the drooping root portion 125 is provided on the side surface, and the mist supply pipe 120 provided inside the cultivation pipe 101, the atomizing liquid tank for storing the nutrient solution, and the nutrient solution is atomized by ultrasonic vibration. And an ultrasonic atomizer for supplying the atomized nutrient solution (mist 126) to the mist supply pipe 120, and an ejection hole 124 is provided. It is shaped like a countersink. [Selection] Figure 2【課題】霧化した養液を植物の根部に供給する噴き出し穴を有する霧供給管を栽培管の内部に備える超音波霧化栽培装置において、復水して水滴になった霧によって噴き出し穴が目詰まりすることを防ぐ超音波霧化栽培装置を提供する。【解決手段】超音波霧化栽培装置は、植物１０６の苗を保持するパネル１２１で上面が構成され、植物１０６の根部１２５が内部に下垂する中空の栽培管１０１と、栽培管１０６の内部に下垂する根部１２５に対応する噴き出し穴１２４が側面に設けられ、栽培管１０１の内部に設けられる霧供給管１２０と、養液を貯留する霧化液槽と、養液を超音波振動で霧化する超音波振動子と、超音波振動子を振動させる発振器とを有し、霧化した養液（霧１２６）を霧供給管１２０に供給する超音波霧化器とを備え、噴き出し穴１２４が皿座ぐり状に形成されている。【選択図】図２
