PROBLEM TO BE SOLVED: To provide an insulation structure material that can reduce the factor of environmental burden which is a fate of insulation structure material that constitutes an electric component and an electronic component made mainly of a thermosetting matrix resin and an inorganic filler, which are essentially required of durability. SOLUTION: The insulation structure material contains a reactive organic filler, which is made of a cellulose derivative or a hemicellulose derivative that is transversion refined from a wooden resource as an original raw material, 5-100 mass % to the resin component, other than the thermosetting matrix resin and the inorganic filler.
