PROBLEM TO BE SOLVED: To provide a new epoxy resin capable of imparting excellent flame-retardance and hydrolysis resistance.;SOLUTION: The epoxy resin is produced by reacting a phenolic compound with a compound having glycidyl group. The phenolic compound is a phosphazene-modified phenolic compound containing a group expressed by general formula (1) (R is a 1-15C alkyl or the like; R1 is H or OH; A is CHR2 or the like; R2 is H, a 1-6C alkyl or the like; X is O or S; Y1 is N=P(XR)3 or N=P(X)XR; Y2 is P(XR)4 or P(X)(XR)2; Y1 and Y2 may be bonded together to form a ring; and (n) and (m) are each an integer of 0-9,999 provided that 2≤m+n≤9,999).;COPYRIGHT: (C)2004,JPO
