摘要： PROBLEM TO BE SOLVED: To prevent the passages of heat exchanging plates from being closed by excessive brazing materials when the heat exchanging plates 8, intermediate plates and end plates are laminated and brazed. SOLUTION: At least one face of adjacent heat exchanging plates 8. intermediate plates 9 and end plates 10 is plated with a nickel brazing material including phosphor. While the respective plates 8 to 10 are laminated, the temperature of a furnace is raised so that the reaction layers of copper and nickel of the respective plates 8 to 10 are formed and the plates 8 to 10 are bonded together. Thus, since molten layers during brazing can be made thin and uniformly formed during brazing, the brazing material can be prevented from closing passages 8a during brazing.

摘要： PROBLEM TO BE SOLVED: To realize both high pressure resistance of a main current terminal and reduction in inductance. SOLUTION: Main current terminals 31, 32 electrically coupled with a main electrode of an IGBT element 27 loaded on a power board 30 are projected outward from a side wall of a case 21. The main current terminals 31, 32 are flat-shaped having main portions of the same plan view contour, and are arranged in parallel to and overlapped with each other. Thus, the inductance of the main current terminals 31, 32 may be restrained to a low level. An insulating material 33 is inserted between portions of the main current terminals 31, 32 which protrude outward from the case 21. The insulating material 33 protrudes outward from the plan view contours of the main current terminals 31, 32. Thus, the pressure resistance of these portions of the main current terminals 31, 32 may be maintained at a high level. Since an electrically insulating filler 43 is filled within the case 21, the pressure resistance of portions of the main current terminals 31, 32 which are housed in the case 21 may also be maintained at a high level.
