This study is to find out non verbal communication factors of family restaurants and to clarify the effects of each factor on brand image and brand trust. The analyses show that there are four non verbal communication factors of family restaurants: body language, space language, intent language and physical appearances. In the relationship between non verbal communication and brand image, the four non verbal communication factors all have influences on brand image. Of all, body language has the most effect on brand image and is followed by space language, intent language and physical appearances in the effect on brand image. In the relationship between non verbal communication and brand trust, only body language and physical appearances except space language and intent language have influences on brand trust. Brand image has significant impact on brand trust. Space language and intent language out of the four non verbal communication factors have no direct effect on brand trust, but they have indirect effect on brand trust through brand image.
