Abstract:
A substrate for a power module ( 100 ) of the present invention includes a metal substrate ( 101 ), an insulating resin layer ( 102 ) provided on the metal substrate ( 101 ), and a metal layer ( 103 ) provided on the insulating resin layer ( 102 ). The insulating resin layer ( 102 ) includes a thermosetting resin (A) and inorganic fillers (B) dispersed in the thermosetting resin (A), a maximum value of a dielectric loss ratio of the insulating resin layer ( 102 ) at a frequency of 1 kHz and 100° C. to 175° C. is equal to or less than 0.030, and a change in a relative permittivity is equal to or less than 0.10.

Claim (Index 3):
The substrate for a power module according to  claim 1 ,\n wherein a total amount of ions in the insulating resin layer, which is measured by analyzing extracted water obtained under the following condition using an ion chromatograph is equal to or less than 30,000 ppm, and the ions are one or more selected from Li + , Na + , NH 4 + , K + , Ca 2+ , Mg 2+ , F \u2212 , Cl \u2212 , NO 2 2\u2212 , Br \u2212 , NO 3 \u2212 , PO 4 3\u2212 , SO 4 2\u2212 , (COO) 2 2\u2212 , CH 3 COO \u2212 , and HCOO \u2212 , (Condition) Pure water (40 mL) is added to the frost-shattered insulating resin layer (2 g), and is extracted with a hot water at 125\u00b0 C. for 20 hours, thereby obtaining extracted water.
