<p>PROBLEM TO BE SOLVED: To obtain a material which solves the conventional technical problems such that high molecular weight polymers are hard to obtain and thus the resulting insulating films have inferior mechanical properties such as tensile strength and further become easily attacked with solvents, and the like, and which can form insulating films having excellent mechanical properties as well as excellent insulating properties. SOLUTION: An insulating resin film-forming composition which is used comprises a polymer of a fluorine-containing polybenzoxazole whose both terminals are capped each with a thermosetting reactive group and cause crosslinking by the curing reaction by heat.</p> |
