To provide a thermally conductive material improved in its characteristics and to provide a production method of the thermally conductive material.SOLUTION: The thermally conductive material includes a first inorganic filler, a second inorganic filler and part of a coupling agent in which the first inorganic filler and the second inorganic filler are bonded with each other at one or a plurality of binding sites and are bonded with each other at one binding site by one part of a coupling agent. The production method of the thermally conductive material includes providing an inorganic filler having a hydroxy group and mixing the inorganic filler with a coupling agent having at least two groups coupling with the hydroxy group to bond the inorganic filler with the coupling agent by dehydration condensation.SELECTED DRAWING: Figure 1 【課題】特性を向上させた熱伝導性材料及びその製造方法を提供する。【解決手段】第１の無機フィラーと、第２の無機フィラーと、カップリング剤部分を含み、前記第１の無機フィラーと前記第２の無機フィラーが、１つもしくは複数の結合部位において互いに結合されており、１つの結合部位においては１つの前記カップリング剤部分によって結合されている、熱伝導性材料、並びに熱伝導性材料の製造方法であって、ヒドロキシ基を有する無機フィラーを提供すること、前記無機フィラーを前記ヒドロキシ基とカップリングする基を少なくとも２つ有するカップリング剤と混合して、脱水縮合により前記無機フィラーとカップリング剤を結合させることを含む方法。【選択図】図１
