    摘要: A substrate for a light-emitting diode comprising a metal base with a thickness of a predetermined value or more is constituted so that the thickness of a top conductor for an electrical connection with a light-emitting diode (LED) in a predetermined range falls within a predetermined range and the thickness of an insulation layer which electrically insulates the metal base and the top conductor and the thickness of the top conductor meet a predetermined relation. Thereby, a substrate for a light-emitting diode which can show a high heat dissipation capacity by achieving a low thermal resistance as the total thermal resistance of the whole substrate without reducing an insulation reliability and high-humidity reliability of the substrate is provided.

    摘要: The present invention is directed to stably achieve a good thermal conductivity in a glass-ceramic composite material in which aluminum nitride particles are used as filler particles. The glass-ceramic composite material according to the present invention includes a glass matrix and filler particles, each of which is formed by an aluminum nitride particle having a surface layer on which an oxide film is formed, and arranged in the glass matrix. The present invention has characteristic features that the filler particle has a cornerless smooth surface, and that a percentage of the number of filler particles having a sphericity of 0.8 or greater, which is a value of a minor diameter divided by a major diameter, is higher than or equal to 70% on the condition where any fine particle of which particle diameter is smaller than 0.5 μm is excluded from the number of the filler particles.
