PROBLEM TO BE SOLVED: To provide an electrically insulating resin composition which exhibits excellent flexibility and adhesion to a substrate, has high heat resistance and humidity resistance, can bear a high-temperature treatment at the time of soldering and forms an electrically insulating layer stably serviceable for a long period of time even under severe environments of high temperatures and vibration in an automobile. SOLUTION: The electrically insulating resin composition is caused to contain at least a rubbery polymer (A) comprised of a copolymer of a vinyl aromatic compound with a conjugated diene compound, a polymerizable monomer (B) bearing at least one reactive double bond at its end and an oligomer (C) having a cyclic structure and a reactive unsaturated bond in the molecule, and is compounded so that the hardness D of the organic component contained therein is at most 75 after cured. Thus, the electrically insulating layer endowed with excellent flexibility, adhesion, humidity resistance and heat deterioration resistance is formed. COPYRIGHT: (C)2006,JPO&NCIPI |
