A method for producing a norbornene derivative includes forming a Mannich base represented by any of general formulae (5) to (7) by reacting a carbonyl compound represented by any of general formulae (1) to (3) and an amine compound represented by general formula (4) with each other in an acidic solvent, to thereby obtain a reaction liquid comprising the Mannich base in the acidic solvent, wherein the acidic solvent comprises a formaldehyde derivative and 0.01 mol/L or more of an acid represented by formula HX; reacting the Mannich base and a diene compound represented by general formula (8) with each other by adding an organic solvent, a base in an amount of 1.0 to 20.0 equivalents to the acid, and the diene compound to the reaction liquid, and then heating the reaction liquid, to thereby form the norbornene derivative represented by any of general formulae (9) to (11).
