PROBLEM TO BE SOLVED: To obtain a thermosetting resin composition which achieves UL94V-0 flame retardancy while containing a halogen and an antimony compound each in a content of 0.25 wt.% or less and which exhibits excellent Tg and heat resistance. SOLUTION: The thermosetting resin composition is characterized in that it is a thermosetting resin containing (A) 5-80 pts.wt. of an epoxy resin, (B) 0-80 pts.wt. of a compound having a dihydrobenzoxazine ring, and (C) 5-80 pts.wt. of a polycondensation product of a phenol, a compound having a triazine ring, and an aldehyde, with the sum of (A), (B) and (C) of 100 pts.wt. and that 5-80 pts.wt. of the epoxy resin is (D) an epoxy resin containing phosphorous.
