Abstract (in Japanese) (See Japanese page) 
(in English) Social media users can widely disseminate information, potentially affecting societal trends. Therefore, understanding factors affecting information diffusion in social media is important for successful viral marketing campaigns. In this paper, we focus on the community structure of social networks among Twitter users and investigate how that structure affects the speed of diffusion by retweets. Extracting communities among sampled Twitter users, we investigate differences in diffusion speed between tweets with many intra-community retweets and those with many inter-community retweets. Consequently, we show that tweets with many intra-community retweets tend to spread slowly. We also use community structures in Twitter social networks to tackle the tasks of predicting time intervals between a first tweet and its $N$-th retweet. We show that the community structure features in a social network are effective for predicting information diffusion speed.
