To provide a refrigerator on which an optical sensor unit capable of performing detection at a low cost with a small space without providing a large and expensive imaging apparatus having complicated image processing algorithm as described in the patent literature 1 when detecting a color balance of food products in a storage part is mounted.SOLUTION: A refrigerator includes a storage part, a light source irradiating food products stored in the storage part with visible light, and a light sensor receiving irradiation from the light source and receiving reflected light. The light sensor includes a determination part determining a color balance in the storage part from a wavelength spectrum of the received light.SELECTED DRAWING: Figure 2 【課題】本開示は、収容部の食品の色彩バランスを検知する場合に、特許文献１のように、大型で高価、更に画像処理アルゴリズムが複雑な撮影装置を設けることなく、安価で、省スペースで検知可能な光センサーユニットを搭載した冷蔵庫を提供する。【解決手段】本開示における冷蔵庫は、収容部と、収容部に収容した食品に可視光を照射する光源と、光源からの照射を受けて、反射された光を受光する光センサーと、を備えた冷蔵庫であって、光センサーは受光した光の波長スペクトルから収容部内の色彩バランスを判定する判定部を備える。【選択図】図２
