Description of the Related Art Epoxy resin compositions used in the field of electronic materials such as semiconductor encapsulants and circuit boards contain some curing agents, curing accelerators, modifiers, fillers, etc. in the epoxy resin. A blended product is used. In such applications, low water absorption, low dielectric constant, and excellent heat resistance are required. It is also known from JP-A-54-18000 to blend a petroleum resin as a modifier with an epoxy resin. However, in these methods, it is not possible to improve the drawbacks of the epoxy resin such as high water absorption and dielectric constant without sacrificing other physical properties such as heat resistance (glass transition temperature) and dimensional stability (coefficient of linear expansion). could not. In recent years, semiconductors are becoming more and more surface-mounted, and semiconductor encapsulating materials are required to have resistance to soldering heat. However, when the water absorption of the epoxy resin composition is high, water expands and vaporizes during immersion of the solder, causing cracks. Further, a circuit board such as a printed circuit board has a problem of heat generation when a high frequency is applied, which is caused by a high dielectric constant of the epoxy resin composition. Although it is in the field of adhesives, it is known to mix a modified hydrocarbon resin as a modifier into an epoxy resin-based adhesive (JP-A-2-235977).
