Summary:[Problem] To provide a mannose extraction method by which it is possible to very easily extract high-purity mannose from a plant-based raw material by performing a 2-stage hydrolysis treatment on the plant-based raw material. [Solution] Mannose is extracted from a plant-based raw material having been subjected to: a first hydrolysis step S1 in which a plant-based raw material M1 and a first acid catalyst A1, which is a weak acid or a diluted strong acid, are mixed and heated; a separation step S2 in which a reaction product M2 obtained from the first hydrolysis step is separated and recovered; and a second hydrolysis step S3 in which the reaction product obtained from the separation step and a second acid catalyst A2, which is a weak acid, a diluted strong acid, a strong acid, or a solid acid, are mixed and heated.
