PURPOSE:To improve electric conductivity of an electric conductive thin plate, proved with numerous penetrating holes by electronic beam processing, by being joined to another electric conductive thin plate. CONSTITUTION:An electric conductive thin plate is provided with many penetrating holes by being processed using electronic beam or laser which takes high energy concentration and is able to control radiating energy, processing position and energy-focusing beam, etc., and then, thus prepared thin plate is joined to another electric conductive thin plate 3. |
