A culture apparatus is provided which can suppress condensation on walls of a culture space and the like to suppress adverse effects on a culture material. In the culture apparatus having a culture space formed in a heat insulating box main body, a humidification water reservoir for humidifying the culture space is disposed in the heat insulating box main body. A heat transfer condensation member in which a condensation portion at one end and a cooling portion at the other end are integrated is disposed such that the cooling portion is disposed outside the heat insulating box main body, while the condensation portion is disposed inside the culture space. The condensation portion is disposed so that condensed water on the surface thereof is led into the humidification water reservoir. The cooling portion has an electronic cooling element for cooling the cooling portion by the Peltier effect, to make moisture condensed on the condensation portion and a connection portion in the vicinity of thereof flow downward into the humidification water reservoir and repeatedly usable as humidification water.
