Abstract

One aspect of the present invention is a resin composition containing a thermosetting resin, a curing agent that reacts with the thermosetting resin, and a flame retardant, in which the flame retardant contains a compatible phosphorus compound that is compatible with a mixture of the thermosetting resin and the curing agent, and a non-compatible phosphorus compound that is not compatible with the mixture, a content of the compatible phosphorus compound is 1 to 3.5 parts by mass per 100 parts by mass of a total of the thermosetting resin and the curing agent, and a content of the non-compatible phosphorus compound is 14 to 30 parts by mass per 100 parts by mass of the total of the thermosetting resin and the curing agent.
