To provide an electric field forming panel for use in a domestic refrigerator capable of adjusting the environment of a storage room of a household refrigerator so as to cause supercooling, and a household refrigerator fitted with the electric field forming panel.SOLUTION: The electric field forming panel 1 used for the domestic refrigerator 10 according to the present invention comprises a mesh-like flat electrode having flexibility, a first panel material covering one side of the flat electrode, A panel body having a second panel member 9 covering the other side, and an insulating material disposed between the first panel member and the flat electrode. In the electric field forming panel 1, when a voltage of 1 kV to 5 kV is applied to the planar electrode with a sinusoidal waveform having a frequency of 48 Hz to 62 Hz to the planar electrode, the electric field forming panel 1 generates a voltage of 0 mV to 3 m from the surface of the planar electrode on which the insulating material is not disposed. An electric field space having an electric field strength of 3 kV / m to 15 kV / m is formed and the environment of the electric field space is adjusted to a state where supercooling in which the water is in a non-frozen state occurs at a temperature below the freezing point.(FIG.【課題】家庭用冷蔵庫の貯蔵室の環境を過冷却が生じるように整えることが可能な家庭用冷蔵庫に使用する電場形成パネル及びこの電場形成パネルを取り付けた家庭用冷蔵庫を提供する。【解決手段】本考案の家庭用冷蔵庫１０に使用する電場形成パネル１は、柔軟性を有し、メッシュ状の平面電極と、この平面電極の一方側を覆う第一パネル材、及び平面電極の他方側を覆う第二パネル材９を有するパネル本体と、第一パネル材と平面電極との間に配置される絶縁材を備えている。そして、電場形成パネル１は、平面電極に周波数４８Ｈｚから６２Ｈｚの正弦波形で１ｋＶから５ｋＶの電圧が印加されることで、平面電極の絶縁材が配置されていない側の表面から３ｍ以内に０．３ｋＶ／ｍから１５ｋＶ／ｍの電界強度を有する電場空間を形成し、電場空間の環境を氷結点以下の温度で水が非凍結状態となる過冷却が起こる状態に整える。【選択図】図３
