| titleOfInvention | Polyimide precursor, polyimide precursor composition, polyimide resin and electronic component |
| abstract | An object of the present invention is to provide a polyimide resin precursor which can form a film having excellent flatness on a substrate having fine unevenness, has a low dielectric constant, low moisture absorption, and has excellent environmental stability. SOLUTION: The following general formula (DA2) (X 2 represents a perfluoroalkylene group, a perfluoroalkylidene group, a sulfonyl group, or a single bond, and R 0 represents a fluoro group or an unsubstituted or substituted with a fluoro group. R 2 represents a fluoro group, an unsubstituted or substituted aliphatic hydrocarbon group or a hydrogen atom, at least one of which is a fluoro group or an aliphatic hydrocarbon substituted with a fluoro group; A and b are integers of 0 to 3), and an amine component containing 0.10 mol equivalent or more of a fluorinated aromatic diamine compound represented by the following formula: and 0.80 mol of tetracarboxylic dianhydride A polyimide precursor having a structure obtained by polymerizing an acid anhydride component containing at least an equivalent amount.
