Abstract

Official abstract text for this publication.

Provided are a resin composition, a cured product, a prepreg, a metal foil-clad laminate, a resin composite sheet, a printed wiring board, and a semiconductor device. The resin composition contains a resin (A) having a terminal group represented by Formula (T1) and having an indane skeleton, and a polyphenylene ether compound (B) having an unsaturated carbon-carbon double bond at a terminal, wherein a mass ratio of a content of the resin (A) to a content of the polyphenylene ether compound (B); i.e., resin (A)/polyphenylene ether compound (B) is 5/95 to 70/30. In Formula (T1), Mb each independently represents a hydrocarbon group having from 1 to 12 carbons which may be substituted with a halogen atom; y represents an integer of 0 to 4; and * represents a bonding position with another moiety.
