To provide a moisture content observation device that accurately estimates a moisture content in a plant, and quantitatively and visually presents a chronological transition of the moisture content.SOLUTION: A moisture content observation device comprises a mixture of resins and saccharides having an absorption spectrum comparable to an absorption spectrum of water at respective wavelengths of near-infrared laser reference light of a first wavelength characterized by hardly being absorbed into moisture and near-infrared laser measurement light of a second wavelength characterized by easily being absorbed into moisture, as a reference for deriving a moisture content in all irradiated positions of observed sites of a plant.SELECTED DRAWING: Figure 2 【課題】植物に含まれる水分量を高確度で推定し、その水分量の時系列の推移を定量的かつ視覚的に提示する水分量観察装置を提供する。【解決手段】植物の観察部位の全照射位置に含まれる含水量を導出するための基準として、水分に吸収され難い特性を有する第１波長の近赤外レーザ参照光及び水分に吸収され易い特性を有する第２波長の近赤外レーザ測定光の各波長に対する水の吸収スペクトルと同等の吸収スペクトルを有する糖類と樹脂との混合物を備える水分量観察装置。【選択図】図２
