A plant raising apparatus (100): a light source (4) that emits light traveling toward an aboveground part (3a) of a plant (3)； a heat insulating portion (5) that has a light transmitting property and that partitions a space at a side of the light source (4) and a space at a side of the aboveground part (3a)； and an air blowing mechanism (6) that generates an airflow at a space between the light source (4) and the heat insulating portion (5). Thereby, it is suppressed that the heat of high temperature air staying above the heat insulating portion (5) having a light transmitting property adversely affects the plant (3).
