PROBLEM TO BE SOLVED: To obtain a resin compound for casting capable of providing a compound material having temperature stability, slight strain in a large area and dimensional stability by including a glycidyl ether-containing resin and an epoxy resin having another specific structure. SOLUTION: This resin compound for casting comprises (A) a glycidyl ether- containing resin and (B) an epoxy resin having at least one different biphenylene structural element and/or dicyclopentadiene structural element. The amount of the component B mixed is preferably 10-70 pts.wt. For example, bisphenol A-diglycidyl ether as the component A in an amount of 50 pts.wt. is incorporated with 50 pts.wt. of the epoxy resin component having a biphenyl structural element or an epoxy resin component having a dicyclopentadiene structural unit as the component B to give the objective composition. Consequently the compound is effectively usable for an electronic part, a sensor, a printed-wiring board, etc.
