Abstract:
The present invention provides a ceramic laminate having excellent mechanical properties, heat dissipation property, insulating property, heat resistance and anti-reactivity, and particularly an insulative heat dissipating body having an excellent thermal cycle reliability and a high withstand voltage. The ceramic laminate  1  according to the present invention is a ceramic laminate in which a ceramic film  3  is formed on a metal layer  2 , wherein the ceramic film  3  has a minimum film thickness of 1 μm or more, contains silicon nitride and inevitable impurities, and has silicon nitride crystal grains having an average grain size of 300 nm or less in the film thickness direction and an average grain size of 500 nm or less in the in-plane direction. As a result, the present invention can provide a ceramic laminate having excellent mechanical properties, heat dissipation property, insulating property, heat resistance and anti-reactivity, and particularly an insulative heat dissipating body having an excellent thermal cycle reliability and a high withstand voltage.

Claim (Index 6):
The ceramic laminate according to  claim 1 , wherein the ceramic film contains silicon nitride whose proportion of \u03b2-silicon nitride in the silicon nitride exceeds 50 wt %, and inevitable impurities.
