For heat transfer performance improvement at boiling area, minute unevenness with the various shapes to the generating surface is proposed in pool boiling. Growth of an air bubble influences big by the minute difference in the shapes. So it's the current state to predict correct heat transfer characteristics by an experiment. The purposes of this study are the specification of the minute unevenness which reduces nuclear boiling arrival and consideration of the mass production method. This report is concerned with function surface creation method which improves heat transfer characteristics and building of an evaluation system, and will be reported about those results.
