摘要： An insulating member has an insulating layer in the form of a thin ceramic plate made of at least one of SiC, Si₃N₄, AℓN and Aℓ₂O₃ ad having a thickness not less than 0.1 mm and not more than 2.0 mm, and cushioning layers provided on both sides of the insulating layer through brazing alloy for relieving thermal stress. An electric part can be made of such an insulating member. The insulating member is disposed between a conductive substrate and a conductive member and brazed thereto.

摘要： A nitrogen-containing sintered hard alloy includes at least 75 percent by weight and not more than 95 percent by weight of a hard phase containing Ti, a group 6A metal and WC in a prescribed composition, and at least 5 percent by weight and not more than 25 percent by weight of a binder phase containing Ni, Co and unavoidable impurities, and contains at least 5 percent by weight and not more than 60 percent by weight of Ti in terms of a carbide or the like, and at least 30 percent by weight and not more than 70 percent by weight of a metal belonging to the group 6A of the periodic table in terms of a carbide, while the atomic ratio of nitrogen/(carbon + nitrogen) in the hard phase is at least 0.2 and less than 0.5, and the nitrogen-containing sintered hard alloy is provided with a soft layer containing a binder phase metal and WC in its outermost surface, and has a layer which is hardly provided with the hard phase containing WC in a portion immediately under the soft layer in a thickness of at least 3 mu m and not more than 30 mu m. According to this composition, it is possible to provide a nitrogen-containing sintered hard alloy which can be employed as a cutting tool having high reliability with no surface coating also in working under conditions bringing a strong thermal shock.
