PROBLEM TO BE SOLVED: To provide a polyimide which has excellent adhesiveness and excellent bonding strength in bonding at low temperatures, to provide a heat-resistant adhesive comprising this polyimide, a polyimide film, an adhesive insulating tape, and a metal laminate. SOLUTION: There are provided the polyimide having repeating units represented by formula (1), the heat-resistant adhesive comprising this polyimide, the polyimide film, the adhesive insulating tape, and the metal laminate. In formula (1), m is 0-4; n is 3-7; Y is a tetravalent organic group; R<SP>1</SP>is a halogen or a hydrocarbon group; and hetero atoms which bond aromatic rings together are bonded to carbon atoms at ortho or meta position to each other in at least one aromatic ring, provided that when n=3, these hetero atoms are bonded to the carbon atoms at ortho or para position to each other in all the aromatic rings.
