Provided is a culture apparatus capable of minimizing condensation on the culturing-space wall surfaces and the like, and minimizing adverse effects on the cultured product. A culture apparatus having a culturing space formed in the body of a thermally insulated box is provided with a humidification water reservoir for humidifying the interior of the culturing space, and a heat-transmitting condensation member passing through the body of the thermally insulated box and having one end thereof positioned inside the culturing space and the other end thereof positioned outside the thermally insulated box body. Therein, the heat-transmitting condensation member is positioned in a manner such that a condensation part thereof positioned inside the culturing space slants downward toward the one end thereof, and the one end thereof is positioned so as to guide condensed water, which condenses on the surface of the condensation part, into the humidification water reservoir.
