PURPOSE:To enable the sure mounting of a cover member on an insulating substrate, by using two magnetic materials to hold the cover member and the insulating substrate pressingly in a heating atmosphere and using a permanent magnet as at least one of both these magnetic materials. CONSTITUTION:A brazing material is placed between an insulating substrate 1 and a covey member. In succession, these are pressed and moved in a heating atmosphere to melt the brazing material 4. When the substrate 1 and the cover member 3 are moved in the heating atmosphere, they are held pressingly by permanent magnets 11, 12 and cooled afterwards. The cover member 3 is thus mounted on the substrate 1. Since two uniform pressing forces can be applied in the direction opposite to each other perpendicularly to the cover member 3 on the substrate 1, the cover member 3 can be surely mounted on the substrate 1.
