Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a refrigerator including a substrate assembly with high light utilization efficiency.SOLUTION: A plurality of LEDs configured to emit light laterally are provided from both right and left side surfaces of a light guide plate 50 with a predetermined distance. The light guide plate 50 has a plurality of light extraction units at positions corresponding to each operation display unit in right and left directions, the light extraction unit configured to extract light toward the operation display unit. At a center 51M in a vertical direction of the light extraction unit positioned on one end side in the right and left directions, irradiation regions from at least two LEDs approaching the light extraction unit are configured to be overlapped with each other.SELECTED DRAWING: Figure 11 【課題】光の利用効率を高めた基板組立体を備えた冷蔵庫を提供する。【解決手段】横向きに照射されるＬＥＤが、導光板５０の左右両側面から所定距離を置いてそれぞれ複数設けられ、導光板５０は、各操作表示部に対応する位置において操作表示部に向けて光を取り出す光取出部を左右方向に複数有し、左右方向の一端側に位置する光取出部の上下方向中央５１Ｍでは、光取出部に近接する少なくとも２つのＬＥＤによる照射領域が重なるようにした。【選択図】図１１
