Abstract
The phenolic resin composition of the present invention includes a novolac-type phenolic resin, a resorcinol resin, and a curing agent, and is of a solid form. The mixing ratio of the resorcinol resin is preferably more than or equal to 1 part by mass and less than or equal to 100 parts by mass with respect to 100 parts by mass of the novolac-type phenolic resin. The mixing ratio of the curing agent is preferably more than or equal to 5 parts by mass and less than or equal to 25 parts by mass with respect to 100 parts by mass of a total amount of the novolac-type phenolic resin and the resorcinol resin. The phenolic resin cured product is obtained by heat-curing the phenolic resin composition.
