<P>PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a bonded body of a ceramic member and a finned heat dissipation member having fins which have excellent heat dissipation performance, and are thin, long, finely pitched without lowering the manufacturing efficiency. <P>SOLUTION: The method for manufacturing a bonded body of a ceramic member and a finned heat dissipation member comprises putting a ceramic base 10 between a thin aluminum plate 21 and a thick aluminum plate 31 via an aluminum alloy solder, brazing them with the solder to obtain a partly finished bonded body 100a, etching the thin aluminum plate 21 into a metal layer for wiring having a specific pattern and forming fins 41 on the surface of the thick aluminum plate 31 by lancing. Since the fins 41 are not present yet during the brazing step, they are not deformed e.g. by buckling. The bonded body, therefore, has thin and finely pitched fins. <P>COPYRIGHT: (C)2012,JPO&INPIT |
