Joining of the dissimilar materials is necessary and important from a manufacturing viewpoint. Therefore, the authors have developed a new laser direct joining method between metals and plastics. In this research, such joining was applied to join Si3N4 ceramic and PET engineering plastic, although the metal was replaced by the ceramic. The shear strength of the joints was 3100 N, which was strong enough to elongate PET plates of 2 mm thickness and 30 mm width. It was confirmed that this laser joining process was effective to directly produce a strong dissimilar material joint of a ceramic and an engineering plastic.
