According to the present invention, there is provided an electronic component part comprising (i) a high thermal conductivity ceramic circuit board, (ii) terminal pins located over said circuit board, and (iii) a metal brazing material having metal brazing powder, at least one element selected from the Group IVa elements and a metal having a melting point higher than that of the metal brazing powder, the metal brazing material bonding said board and said pins. According to the present invention, metal, such as input/output terminal pins can very firmly be bonded to ceramic, such as a circuit board, within an atmosphere of, for example, N 2 gas without the scattering of any brazing material in which case, unlike the prior art method, vacuum furnace is not employed. |
