PROBLEM TO BE SOLVED: To provide a high dielectric elastomer composition having superior dielectric characteristics, which is a mixture of high dielectric ceramic which can be obtained by combustion composing at low cost and can make wide a particle diameter distribution and in which a high-density filling can be possible, and to provide a manufacturing method for the composition and a high-frequency electronic component using the material. SOLUTION: The high dielectric elastomer composition is a mixture of elastomer with high dielectric ceramic, containing as composing elements at least Sr, Li, Ti, O and Nd, and these high dielectric ceramic having, at a molar composition ratio, SrO:16, Li<SB>2</SB>O: x, Nd<SB>2</SB>O<SB>3</SB>: y, Re<SB>2</SB>O<SB>3</SB>: (12-y), TiO<SB>2</SB>: 63 (wherein Re is for a rare earth element, other than Nd, and 8≤x≤14 and 10≤y≤12) can be obtained, by using a reaction material containing at least Ti powder with a specific surface area of 0.01 to 2 m<SP>2</SP>/g, an ion-binding substance, SrCO<SB>3</SB>, Li<SB>2</SB>CO<SB>3</SB>, Nd<SB>2</SB>O<SB>3</SB>in a combustion synthesis method at 1,500°C or higher of an adiathermant flame temperature.
