Agents that has been addressed social issues are frequently unable to scale up their activities. Therefore, the effect of social innovation has been limited to specific regions. It is necessary to build cooperative relationships between various organizations in order to diffuse social innovation. The key point for making this function effectively is interorganizational trust on networks. The purpose of this paper is to consider the following two research questions. The first question addresses what type of interorganizational trust is built by networks and how it develops. The second addresses how interorganizational trust facilitates the development of networks. The analytical method used in this paper is a qualitative analysis based on a case study. I made a comparative analysis of the case which interorganizational network has developed and the case in which it has collapsed. The following results were obtained. Interorganizational trust built by networks is affective trust. The networks make it possible to build affective trust quickly, and make the relationships between organizations long-term and strong. Cognitive trust is required when building networks and is built by temporary interaction between organizations. By interacting with cognitive trust and affective trust, the level of affective trust increases and activities in the networks evolves. This means that network members are motivated to develop their network. As this motivation develops to the behavioral level, the possibility of social innovation diffusion will increase.
