PROBLEM TO BE SOLVED: To provide an illuminator with high raising effect on a subject being raised such as a plant.SOLUTION: An illuminator according to an embodiment is an illuminator for raising which emits an emission spectrum including: a first wavelength component having light intensity in a range from 600nm to 700nm； a second wavelength component having light intensity in a range from 500nm to less than 600nm, and a third wavelength component having light intensity in a range from 400nm to less than 500nm. The illuminator satisfies the conditions that a content (PPF-R) of a photosynthesis-effective photon flux of the first wavelength component is 50% or more and 65% or less, a content (PPF-G) of a photosynthesis-effective photon flux of the second wavelength component is 30% or more and 40% or less, and a content (PPF-B) of a photosynthesis-effective photon flux of the third wavelength component is 1% or more and 15% or less to photosynthesis-effective photon flux to 3 wavelength components of the first, second and third wavelength components.SELECTED DRAWING: Figure 11【課題】植物等の育成体の育成効果の高い照明器を提供すること。【解決手段】実施形態の照明器は、600nm以上700nm以下に光強度を有する第１の波長成分、500nm以上600nm未満に光強度を有する第２の波長成分、及び400nm以上500nm未満に光強度を有する第３の波長成分を含む発光スペクトルを放出する育成用の照明器である。前記照明器は、前記第１、第２、及び第３の波長成分の３波長成分の光合成有効光子束に対する前記第１の波長成分の光合成有効光子束の含有率（PPF-R）が50%以上65%以下、前記第２の波長成分の光合成有効光子束の含有率（PPF-G）が30%以上40%以下、及び前記第３の波長成分の光合成有効光子束の含有率（PPF-B）が1%以上15%以下の条件を満たす。【選択図】図１１
