An object of the present invention is to provide a novel resin having excellent heat resistance and mechanical properties of a cured product and improved flame retardancy, and a resin composition containing the same. A thermosetting resin having a biphenylene structure and a benzoxazine structure represented by the following general formula (1). (Wherein, R 1 represents an organic group having 1 to 10 carbon atoms, R 2 represents hydrogen or a hydrocarbon group having 1 to 6 carbon atoms, and n represents an integer of 1 to 10). The thermosetting resin may be mixed with other benzoxazine resin, epoxy resin or polyimide resin to form a thermosetting resin composition. [Selection diagram] None |
