In this research, we aimed at developing a survey method to collect micro data in order to analyze spatial information flows. Two types of survey were conducted for the manufactures in Miyagiken area. First, the comparison of two data sets shows no data sets shows no distinct discrepancy in the rate of recording and misrecording contacts between two methods. Therefore, the efficiency of the mail survey is affirmed to collect contact data at practical level. Second, the analysis of purposes of contacts on the mail survey data shows the effective indices of information flows as 'To give an order'/'Meeting' in case of outgoing contact and 'To receive an order'/'Meeting' in case of incoming contact. It is recognized that the rational survey method to collect micro data of information flows, through face-to-face contacts, was well established from the empirical analysis in this investigation.
