摘要：
A tetracarboxylic dianhydride includes: at least one acid dianhydride (A) selected from the group consisting of compounds each having an endo/exo type three-dimensional structure represented by a particular general formula and their enantiomeric compounds each having an exo/endo type three-dimensional structure; and/or an acid dianhydride (B) having an endo/endo type three-dimensional structure represented by a particular general formula, wherein a content of the acid dianhydride (B) in a total amount of the acid dianhydrides (A) and (B) is 30 to 100% by mole in a mole ratio.
