PROBLEM TO BE SOLVED: To provide an insulation film forming material which has superior insulation property, solvent resistance, heat resistance and proper adherence with a substrate, and can be formed into a desired pattern. SOLUTION: The insulation film forming material made of a polymer, thermosetting agent, and a solvent is characterized by that the polymer is made of alkali-soluble resin in a structure shown by a formula (I). In the formula, R1 is H or CH3 , A OA1 or NA2 A3 (A1 , A2 , A3 : H, C1 -C6 alkyl, C6 -C12 aryl, C7 -C12 aralykyl), and k and m are integers larger than 1, and n an integer equal to or larger than 1. |
