A resin composition comprising the following components (a) and (b). (a) have the polyimide precursor of the structural unit represented by following general formula (1), (b) the compound represented by following general formula (2) (in the formula, R 1 is 4 valent organic groups , R 2 is a divalent organic group, R 3 and R 4 are each independently a hydrogen atom, an alkyl group, a cycloalkyl group or a monovalent organic group with a carbon-carbon unsaturated double bond. R 5 represents 1 carbon atom An alkyl group of ∼4, R 6 are each independently a hydroxyl group or an alkyl group with 1 to 4 carbon atoms, a is an integer of 0 to 3, n is an integer of 1 to 6, R 7 is the general formula (3) or ( Any group in 4). In formula (3) or (4), R 8 is an alkyl group with 1 to 10 carbon atoms, or a monovalent organic group derived from hydroxyalkylsilane, and R 9 is An alkyl group having 1 to 10 carbon atoms, a monovalent organic group derived from an aminoalkylsilane, or a heterocyclic group. Each of R 8 and R 9 may have a substituent). |
