PROBLEM TO BE SOLVED: To provide an ultrasonic irradiation device and an ultrasonic irradiation method for performing formation suppression, removal, or sterilization of a biofilm or a pathogen.SOLUTION: An ultrasonic irradiation device 1 includes an ultrasonic wave generation unit 2 for generating an ultrasonic wave and performs formation suppression, removal, or sterilization of a biofilm or a pathogen by radiating the ultrasonic wave generated by the ultrasonic wave generation unit 2 to the biofilm or the pathogen. The ultrasonic wave has a frequency in a range of 0.02-10 MHz and an irradiation intensity in a range of 0.01-10 W/cm. |
