An incubator according to the present invention includes a casing 5, a plurality of rack units 30, an air-blower 10, and partition panels 40. The plurality of rack units include a plurality of trays 33 for holding eggs, and are arranged in the casing 5. The air-blower is arranged on an air-flowing path 6 that is interposed between the plurality of rack units 30. The partition panel are arranged at the boundaries between the rack units 30 and the air-flowing path 6, and face the air-blower 10 side surfaces of the rack units 30 so that air currents that are produced by the air-blower 10 do not flow into/from the rack units 30 through the air-blower-side surfaces of the rack units.本發明實施形態之孵蛋機(1)具備:外殼(5)、和具有乘放種蛋之多數托盤(33)且設置在外殼(5)內之多數框架單元(30)、和設置在被多數框架單元(30)包夾之送風通路(6)上的送風機(10)、和以與框架單元(30)的送風機(10)側之側面相對的方式,設置在框架單元(30)與送風通路(6)交界的隔間板(40),且構成:由送風機(10)所吹送的風不會從側面進入框架單元(30)內。1‧‧‧孵蛋機5‧‧‧外殼6‧‧‧送風通路10‧‧‧送風機11‧‧‧風扇12‧‧‧旋轉葉片13‧‧‧馬達15‧‧‧固定葉片17‧‧‧框體20‧‧‧冷卻手段22‧‧‧加熱手段24‧‧‧冷卻器30‧‧‧框架單元31‧‧‧多層托盤棚32‧‧‧支持框33‧‧‧托盤36‧‧‧腳輪40‧‧‧隔間板40-1‧‧‧隔間板40-2‧‧‧隔間板50‧‧‧溫度感測器52‧‧‧第二溫度感測器
