A method comprising an oximation step of reacting a formylalkenylcyclopropanecarboxylic acid ester represented by the formula (1):
(wherein, R
1
represents an alkyl group optionally having substituent(s) or halogen atom(s), and R
2
represents an alkyl group optionally having substituent(s) or a benzyl group optionally having substituent(s)) and hydroxylamine in a solvent in the presence at least one compound selected from the group consisting of carboxylic acids and carboxylic acid metal salts, to produce a hydroxyiminoalkenylcyclopropanecarboxylic acid ester represented by the formula (3):
(wherein, R
1
and R
2
are as defined above).
