A hydroponic cultivation apparatus, wherein a plant that stores nourishment in an underground portion thereof is raised by hydroponics, including: a nutrient solution flow path provided at a bottom portion of a cultivating container； a partitioning member arranged above the nutrient solution flow path, including a through-hole having a size that a root and a stolon produced from the underground portion of the plant pass therethrough, and supporting the stolon and a tuber extended from underground portion with an upper surface thereof. The hydroponic cultivation apparatus makes the root produced from the underground portion pass through the through-hole from an upper surface side toward a lower surface side of the partitioning member, and immerses the root in the nutrient solution flow path and grows the stolon on the upper surface of the partitioning member and produces the tuber of the plant on the upper surface of the partitioning member.
