    • PROBLEM TO BE SOLVED: To provide a non-halogen and non-antimony flame-retardant resin composition based on a thermosetting resin such as an epoxy resin, good in flame retardancy and also excellent in various properties including moldability and heat resistance, and to provide a cured form using the flame-retardant resin composition.
      SOLUTION: The flame-retardant resin composition comprises a thermosetting resin and an inorganic filler and also at least one of a phosphorus-containing Ti-based coupling agent of the formula(wherein, R
      1 , R
      2 , R
      3 and R
      4 are such that at least one of them is a phosphorus-containing organic group, the other(s) being an organic group each) shown in the Figure, wherein the weight ratio of the coupling agent(s) to the inorganic filler is 0.02-0.2.

    • PURPOSE: To remove impurity gas adhering to the surface of thermoelectric conversion material powder and to prevent the impurity gas from being diffused in the interior of a sintered body during the firing of a temporarily molded material by a methods wherein before the temporarily molded material is fired, the molded material is fired in a reduced pressure atmosphere and at a temperature lower than temperature for firing the molded material. CONSTITUTION: A little amount of a dopant is added to a raw material containing two kinds or more of elements among elements of bismuth(Bi), tellurium(Te), selenium(Se) or antimony(Sb), the dopant and the elements are fully mixed and/or are melted according to the need and after that, they are ground to obtain thermoelectric conversion material powder. This powder is temporarily molded into an optional shape by a normal uniaxial press molding method, for example. A binder of the temporarily molded material is removed by heating as needed. Before the molded material is burned, the molded material is burned in a reduced pressure atmosphere and at a temperature lower than temperature for firing the molded material. Thereby, impurity gas adhering to the surface of the thermoelectric conversion material powder is removed, and the gas is prevented from being diffused in the interior of a sintered body.
