RESIN COMPOSITION FOR PRINTED WIRING BOARD MATERIAL AND PREPREG, RESIN SHEET, METAL FOIL-CLAD LAMINATE, AND PRINTED WIRING BOARD USING THE SAME

摘要

A resin composition used as a material of an insulating layer of a printed wiring board including the insulating layer and a conductor layer formed on a surface of the insulating layer by plating, the resin composition including: an epoxy compound; a cyanate compound; a maleimide compound; an inorganic filler; and an imidazole silane, wherein the maleimide compound includes a predetermined maleimide compound, a content of the maleimide compound is 25% by mass or less based on 100% by mass of a total content of the epoxy compound, the cyanate compound, and the maleimide compound, and the imidazole silane includes a compound represented by the formula (3).
