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