Disclosed is a process for producing 6-aryloxyquinoline derivatives useful as insecticides or fungicides for agricultural and horticultural use. The process comprises a cyclization reaction step of reacting an anthranilic acid derivative represented by general formula (1) with a ketone in the presence of an acid to obtain a quinolone derivative and a condensation reaction step of reacting the quinolone derivative with a halogen compound or an acid anhydride to obtain a quinoline derivative.
