###############################################################################################################################################################################################################################################################Recent development of communication networks based on information technologies has been producing a lot of virtual communities. It is bringing a new kind of social phenomenon, especially on the communities on the world wide webs, such as SNS (Social Networkig Service) and Weblog. It is considered that the SNS and the blogs are kinds of social networks of their users. From a viewpoint of the communication network, they become a new communication infrastructure and their influence become more profound. Because of this, the phenomena or functions observed in such networks are notable. In the latest studies on networks, some close relationships are pointed out between the structure and the function of networks. In this paper, we analyze a structure of a real SNS, comparing with several theoretical network models. We show that the SNS has an unique structure that conventional network models have not represented. Furthermore, taking notice of the function of the network, we estimate a model of the SNS network structure, based on the phenomena that derive from the network structure, as well as the structure itself.
