　This study aims to show the preferable lighting conditions for the appearance of dishes and smooth communications with family in the dining room.　We conducted an experiment on the subjective evaluation under 43 lighting conditions in total, which combined light source, light color, and illuminance. 20 subjects evaluated "Brightness", "Visibility", and "Preference of the appearance" for each object ; dishes on the dining table and the faces of those who sit around the dining table. After, they evaluated satisfaction of lighting conditions. Additionally, they evaluated "Impression of the dining table" using 20 pairs of adjectives of the Semantic Differential method.　The results showed that illuminance, color temperature, and spectral distribution of light source are major factors in the verification of lighting for the dining room.
