  • Publication number: 20150044484
    Abstract: To provide a prepreg that achieves a low dielectric loss tangent, despite the use of a polar solvent. A prepreg produced by impregnating or coating a base material with a varnish comprising an inorganic filler, a polar solvent, and a resin composition principally comprising polyphenylene ether, and subjecting the base material treated to a drying step, wherein the polar solvent content of the prepreg is 3 mass % or less, and a dielectric loss tangent at 10 GHz of a laminated board produced using this prepreg is 0.001-0.007.
