PROBLEM TO BE SOLVED: To provide a phenolic resin which exhibits good moldability and curability and can obtain a cured product having excellent heat resistance, particularly when used as a curing agent for epoxy resins, a method for manufacturing the same, and an epoxy resin curing agent. SOLUTION: This phenolic resin has a repeating unit to be represented by formula (I) (wherein A shows a morphology of a bonded compound having a phenolic hydroxy group) in the molecule, and it is preferred that the weight average molecular weight of the phenolic resin is 300-3,000, and the repeating unit to be represented by formula (I) is≥80 mol% based on the entire phenolic resin.
