Abstract:
Provided is a large-sized silicon nitride sintered substrate and a method for producing the same. The silicon nitride sintered substrate has a main surface  101 a  of a shape larger than a square having a side of a length of 120 mm. A ratio dc/de of the density dc of the central area and the density de of the end area of the main surface  101 a  is 0.98 or higher. The void fraction vc of the central area of the main surface  101 a  is 1.80% or lower, and the void fraction ve of the end area is 1.00% or lower. It is preferred that the density dc of the central area is 3.120 g/cm 3  or higher, the density de of the end area is 3.160 g/cm 3  or higher, and a ratio ve/vc of the void fraction vc of the central area and the void fraction ve of the end area is 0.50 or higher.

Claim (Index 11):
A circuit board including the silicon nitride sintered substrate of  claim 1 , the circuit board having a dielectric breakdown voltage of 8.0 kV or higher and a Weibull coefficient of dielectric breakdown voltage of 6 or higher.
