<P>PROBLEM TO BE SOLVED: To provide an insulating substrate comprising an insulating layer formed by applying a thermal sprayed ceramic powder onto one surface of a conductive substrate, which improves insulation performance at the lateral end face in a simple configuration and at a lower cost. <P>SOLUTION: A taper surface 1Ac is formed at a corner on a first surface 1a of a conductive base material 1A and an insulating layer 7A is formed by applying a thermal sprayed ceramic powder onto the first surface 1a and the taper surface 1Ac, thereby composing an insulating substrate 11A. <P>COPYRIGHT: (C)2013,JPO&INPIT |
