In reflection of the current trend of times requiring the harmonization of nature, human being and scientific technologies, science museum has become more and more familiar to public and demand on it is also increasing. Information on the culture of science and technology is an engine for exploiting the future, particularly in the industrialized, informationalized and specialized society. Thus the science museum, the function of which is to convey such information, should be planned with the purpose of active and progressive communication. This purpose of planning can be achieved through well established process of the exhibition space production. This study focuses on the importance of the exhibition space production in the design of the science museum and proceeds as follows. 1. The concept of the exhibition space production is established following the review of function and the role of science museum. 2. The methods and the media used in the exhibition space production are suggested and the case study is made. 3. The scenarios for the exhibition space production planning are suggested and the effect and importance of the space production is enlightened. The result of this study shows that the space production increases the effectiveness of the exhibition in the science museum and that space production process should be reflected in planning the project.
