The present invention relates to a novel diamine, a novel acid dianhydride, and a novel composition containing a polyimide produced from such diamine and acid dianhydride. Specifically, the present invention relates to an acid dianhydride that has a photosensitive group bonded through the mediation of an alkylene group or a fluoroalkylene group, a diamine that has a reactive group bonded through the mediation of an alkylene group or a fluoroalkylene group, and a polyimide composition that contains a novel polyimide having at least one of such acid dianhydride residue and diamine residue in a molecule thereof. Particularly, an object of the present invention is to provide a novel polyimide that has both photoreactivity and thermoreactivity specific to the reactive group and whose reactive group is selected from the group consisting of: organic groups derived from cinnamic acid, chalcone, furylacryloyl, benzalacetophenone, stilbene, coumarin, and pyrone; allyl; propargyl; ethinyl; CH
