The experimental study on thermocapillary convection of low Prandtl number fluid was carried out to estimate the mode structure after the onset of oscillatory flow. The half-zone liquid bridge of molten tin was used as a experimental configuration. In order to detect very slight temperature changes, the temperature measurement system was improved. Temperature oscillations at the interface between liquid and cold rod were obtained by several thermocouples. The mode structure appeared in a low frequency oscillation region after the onset was presumed from the phase differences among them. The mode structure was supposed to be 2 and rotation with a frequency of 0.008Hz.
