The purpose of this presentation is to clarify the roles of technological accumulation in the process of technological breakthrough by case study. According to previous studies, it is difficult to achieve the technological paradigm shift, which is important in technological breakthrough, because of stickiness to the existing technological paradigm. However, in actual technological breakthroughs, sufficiently accumulated technology according to the existing technological paradigm contributes greatly. Therefore, I considered the hypothesis of the technological breakthrough process and the roles of technological accumulation by detailed analysis of three technological breakthrough cases in development of semiconductor materials for Blue LED. As a result, I present the conclusions that the roles of technological accumulation in technological breakthrough are “to seek out for new key technological parameter outside” and “to know that the obtained key technological parameter is suitable” led by the "detailed map with blind area", a situation in which the mechanism of phenomena is incomplete and cannot be solved, despite the sufficient technological accumulation.
