PROBLEM TO BE SOLVED: To obtain an epoxy resin molding material excellent in dehalogenation, deantimonation and high-temperature releasing characteristics and useful as an electronic device, or the like, by compounding an epoxy resin with a specific cyclic phosphazene as a flame retardant. SOLUTION: This epoxy resin molding material consists essentially of (A) an epoxy resin having two or more epoxy groups in one molecule, (B) a compound having two or more phenolic hydroxyl groups in one molecule, (C) a cyclic phosphazene compound containing formula I and/or formula II [(m) and (n) are each 1-10; R1 to R4 and R5 to R8 are each a (substituted) 1-12C alkyl, aryl or the like; A is a 1-4C alkylene or allylene] as a recurring unit in the main chain skeleton and (D) inorganic filler, and the content of the component D is >=70 wt.% based on total molding material. Furthermore, it is preferable that a molar ratio (m/n) of formula I and/or formula II is (1/0) to (1/4) and the content of the component C is 0.2-5.0% expressed in terms of phosphorus atom amount based on total amount of compounding component excluding the component D.
