Abstract
An easily-administered technology which demonstrates the intrinsic thermal conductivity improvement effect by addition of non-oxide system compound crystal phase (filler particles) and makes it possible to sufficiently raise the thermal conductivity of a glass-ceramics composite material is provided. In the glass phase which constitutes a glass-ceramics composite material, the quantity of aluminum oxide (Al2O3) component is increased under a condition where at least either of zinc oxide (ZnO) component or magnesium oxide (MgO) component exists in a predetermined quantity or more. Thereby, the unintended reaction between a non-oxide system compound crystal phase and a glass phase can be suppressed, and the intrinsic thermal conductivity improvement effect by addition of non-oxide system compound crystal phase (filler particles) can be demonstrated.
