| description | PROBLEM TO BE SOLVED: To provide a resin package based on a thermosetting resin, and having a high dimensional accuracy, low warpage, low thermal expansion and high heat resistance. SOLUTION: This resin composition for molding comprises (A) an epoxy resin having a naphthalene backbone having a prescribed structure, (B) a phenolaralkyl resin-curing agent having a prescribed structure, (C) a curing accelerator and (D) fused silica powder having 10 to 30 μm weight-average particle diameter, wherein the fused silica powder (D) is contained in the molding resin composition in a rate of 80 to 90 mass% and the molding resin composition contains no halogen atom.
