A polyimide precursor having a repeating unit represented by the following general formula (1), wherein R<1> contains a bivalent organic group constituting a diamine having a hexafluoropropylidene group in its molecule represented by the following general formula (2), and the reduced viscosity is from 0.05 to 5.0 d l /g (in N-methylpyrrolidone at a temperature of 30 DEG C, concentration: 0.5 g/d l ), and a polyimide obtained by imidizing said precursor: <CHEM> <CHEM> (wherein R<1> is a bivalent organic group constituting a diamine, A is a hydrogen atom, a linear alkyl group including a methyl group, or a trifluoromethyl group, and n is the number of a substituent on an aromatic ring and an integer of from 1 to 4). |
