摘要： An object of the present invention is to provide a novel photosensitive resin precursor that can be developed with an alkali and ring-closed even at low temperatures, and preferably has excellent thermal properties and excellent electric properties after curing, and also to provide a use application thereof. As means for achieving the object, disclosed are a bismaleimide compound comprising, in one molecule, two partial structures in each of which a carbon atom having a substituent represented by the following formula (A) (wherein Y represents a direct bond or a divalent linking group), and a carbon atom having a hydroxy group are directly bonded to each other, a polymer which is a self-polymer of the bismaleimide compound, and a benzoxazole which is an intramolecular dehydrated ring-closed product of the polymer.
