This disinfectant solution spraying device (1) sprays a disinfectant solution in a bathroom. The disinfectant solution spraying device (1) is provided with an ultrasonic wave generating element (23), a blower device (11) and a guide surface (251). The ultrasonic wave generating element (23) applies ultrasonic wave vibration to the disinfectant solution to generate a disinfectant solution mist. The blower device (11) blows the disinfectant solution mist. The guide surface (251) guides the disinfectant solution mist to a prescribed surface of the surfaces defining the bathroom such that the blown disinfectant solution mist flows along the prescribed surface. The disinfectant solution mist is sent out from the guide surface (251) from the horizontal direction to the upwards direction. Or, the disinfectant solution mist is sent out from the guide surface (251) in the horizontal direction, the diagonally upward direction or the upward direction.除菌液散布裝置（1）將除菌液散布於浴室。除菌液散布裝置（1）具備超音波產生元件（23）、送風裝置（11）與引導面（251）。超音波產生元件（23）對除菌液施與超音波振動，使除菌液之霧產生。送風裝置（11）對除菌液之霧進行送風。引導面（251）以被進行送風的除菌液之霧沿著劃分浴室之面中的既定之面流動的方式，將除菌液之霧引導至既定之面。除菌液之霧自引導面（251）從水平方向遍及至上方向。或者除菌液之霧自引導面（251）被往水平方向、斜上方向或上方向送出。
