A phenolic resin can be obtained by a condensation reaction between a specific trifunctional aromatic compound and a phenolic compound. This resin can be reacted with a curing agent such as a hexamine to give cured articles having excellent heat resistance, electrical properties, wear resistance and chemical resistance, and the phenolic resin is also much more excellent in curing reactivity as compared with conventional techniques.
