The behavior of cavitation bubbles is important in sonoplasma, which is generated by simultaneous microwave and ultrasound irradiation. Sonoplasma is expected to be applied in great many fields, such as high-speed chemical vapor deposition. In this study, the behavior of a single bubble in $n$-dodecane with ultrasonic irradiation was first observed using a charge-coupled-device camera and a stroboscope. In the observation, though sonoluminescence was not confirmed, the bubble was expanded and contracted synchronously with the ultrasonic frequency and was deformed when it contracted to its minimum size. The mechanism of the deformation of the bubble was clarified by numerical analysis. The stability of the bubble can be determined according to initial radius and the amplitude of the sound pressure.
