Abstract
A glass-ceramics composite material suitable for a low-temperature firing use, which has high moisture resistance and thermal conductivity, is provided. In the glass-ceramics composite material which contains aluminum nitride (AlN) particles as a filler, even in a case where boron oxide (BO) is blended as a flux of a glass phase, by adjusting the composition of raw materials which forms the glass phase to a specific conditions to make the crystal phase which contains boron (B) precipitate at the time of firing of the glass-ceramics composite material.
