  • Publication number: 20250034385
    Abstract: The present disclosure provides a thermosetting resin composition and the like, from which is obtained a cured product that excels in dielectric properties with respect to high-frequency radio waves. The thermosetting resin composition and the like of the present disclosure contain a thermosetting resin having a plurality of ethylenically unsaturated groups per molecule. The ethylenically unsaturated groups are carbon-carbon double bonds each containing two carbon atoms. A percentage of a number of ethylenically unsaturated groups in which both of the two carbon atoms are bonded to one or two atoms other than a hydrogen atom by single bonds is 50% or greater, with proviso that the total number of the ethylenically unsaturated groups is 100%. Alternatively, a dielectric loss tangent at 40 GHz of a cured product of the thermosetting resin composition is smaller than a dielectric loss tangent at 10 GHz of the cured product.
