PROBLEM TO BE SOLVED: To provide a plant-growing device in which a sufficient amount of light reaches upper and lower portions of a plant in the plant-growing device without forming a shadow.SOLUTION: A plant-growing device 1 comprises a receiving pan 2 which includes a bottom part 3 having a plant receiving part 4, and a light source part 6 for supplying light to the plant receiving part 4. In order to obtain a condition optimum for growth, the light source part 6 is thin and long, and surrounded by plants mounted on the plant receiving part 4, generates light at a plurality of different heights at higher positions than the bottom part 3, and is disposed at the center of the plant receiving part 4.【課題】生育器内で植物の上方及び下方の部分に、影を作らずに十分な光が届く生育器を提供する。【解決手段】生育器１は、植物受け部４を有する底部３を備える受皿２と、植物受け部４に光を供給するための光源部６とを具備する。成長に最適な条件を得るために、光源部６は細長で、植物受け部４に載置される植物によって周囲が取り囲まれ、底部３よりも高い位置にある異なる複数の高さで光を生成する植物受け部４の中央に配設する。【選択図】図２
