The production in Electronic Materials Industry is under the large influence of the trends in Electronic Industry which is the major field of the demand; Industrial Electronic Appliance which is mainly composed of computer and communication equipments, Consumer Electronic Appliance which is mainly composed of video equipments (Home TV, Video etc.), and Electronic Components & Devices (semiconductors, ICs, display devices). First, the trend of electronic ceramic components is introduced by over-view of Japanese production changes of Electronic Industry and Electronic Materials (the association handling) in past ten years. Second, the demand forecasting of each production which is based on the trend of its related electronic equipment is introduced. Third, the major production groups and the technology trend of electronic equipments & devices which largely influence the technological trend of electronic ceramic components are introduced. Finally, the technology trend of electronic ceramic components is outlined. Only over-view of the field of Industrial Electronic Appliance, the market of Electronic Industry is annually expanding, as operation of Mobile Communication at Sub-microwave band (L band) is starting, Multi-Media era which is information equipment related is coming, and electronics applying in Automobile related equipment is developing. In connection with these, the demand expansion of Electronic Materials and rapid progress of the technology are expected.
