PROBLEM TO BE SOLVED: To suppress unevenness of light irradiated to a cultivation part while suppressing obstruction of an air flow toward a cultivation part where plant seedlings are cultivated in a plant cultivation apparatus. SOLUTION: A plant cultivation device 1 includes a cultivation shelf 2 for cultivating plant seedlings, a light irradiation device 6 for irradiating the cultivation shelf 2 with light, a blower 8 for generating an air flow toward the cultivation shelf 2, and light irradiation. It has a ventilation reflection wall 40 that reflects the light emitted by the device 6 toward the cultivation shelf 2 and allows the airflow generated by the blower device 8 to pass through, and includes a housing 3 that surrounds the cultivation shelf 2.
