<p>The present invention addresses the problem of providing: a polyimide which has excellent transparency, high heat resistance and low linear thermal expansion coefficient at the same time, while exhibiting solvent workability (excellent solubility and film formation performance) by means of a low moisture-absorbing solvent; and a method for producing this polyimide. In order to solve the above-mentioned problem, the present invention provides a polyimide that contains a constituent unit represented by formula (1). (In the formula, each R independently represents a hydrogen atom or an alkyl group having 1-6 carbon atoms, provided that at least one of two R groups bonded to a same benzene ring is an alkyl group.)</p> |
