An insulating member has an insulating layer in the form of a thin ceramic plate made of at least one of SiC, Si.sub.3 N.sub.4, AlN and Al.sub.2 O.sub.3 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.

Insulating member and electric parts using the same

A radiation detecting element comprising a pair of electrode and a semiconductor layer interposed between said pair of electrodes wherein said semiconductor layer comprises a polycrystal diamond having no grain boundary in a direction in which a voltage is applied, and an electric current flows through said semiconductor layer from one electrode to the other without crossing a grain boundary, which element has high sensitivity and a high response speed.
