This study aims to compare the effect of the visual-tactile integration with that of visual-tactile \integration on the sense of self during out of body illusion and points out the importance of the \multisensory integration as a component of the sense of self. This ‘multisensory integration’ is one of \the important factors of bodily self-consciousness, and the other two factors are plausibility, and first-\person-perspective. The result shows that the participants felt illusions significantly more intensively \when visual-auditory / visual-tactile information was presented simultaneously than alternatively. And \it also suggests the possibility that visual-tactile stimulus induces the illusion more than the visual-\auditory stimulus does. Furthermore, when presenting visual-auditory stimulus by irregular rhythms, \females felt the illusions more, and in turn, males felt the illusion more when presenting visual-tactile \stimulus. This result shows the critical difference between the property of audition and touch in out-\of-body illusion. It suggests that the combinations of vision and touch are robust and not changeable, \while those of vision and audition are highly weak. In sum, it is needed to investigate the effect of \audition and other factors on the sense of self in more detail using out-of-body illusion.
