The present invention has been made in view of the circumstances herein. An object of the present invention is to provide: a tetracarboxylic dianhydride which can lead to a polyimide usable as a base resin of a photosensitive resin composition capable of forming a fine pattern and obtaining high resolution without impairing excellent characteristics such as mechanical strength and adhesiveness; a polyimide resin obtained by using the tetracarboxylic dianhydride; and a method for producing the polyimide resin. The tetracarboxylic dianhydride is shown by the following general formula (1).
