Abstract: In order to provide an imide oligomer or the like which can give a cured product exhibiting excellent thermal oxidative stability, an imide oligomer is obtained by reacting together an aromatic tetracarboxylic acid component, an aromatic diamine component, and a terminal capping agent. The imide oligomer contains, in a specified proportion: a compound containing a phenylethynyl group; and a compound containing no carbon-carbon unsaturated bond capable of an addition reaction. One or each of the aromatic tetracarboxylic acid component and the aromatic diamine component contains a component having an asymmetrical and non-planar structure.
