PROBLEM TO BE SOLVED: To provide a polyimide having high heat resistance and transparency, and in addition, capable of peeling off resin layers by a solvent giving a small load to the environment such as a dilute aqueous inorganic alkaline solution. SOLUTION: This polyimide is obtained by reacting at least 1 kind of the compound selected from diamines with at least 1 kind of the compound selected from acid di-anhydrides in an organic solvent, and as an essential component of the diamine, an aliphatic ring-structured diamine having >=1 carboxy group is supplied for the reaction.
