POWER CONSUMPTION REDUCTION STRUCTURE OF BUILDING AND METHOD FOR REDUCING POWER CONSUMPTION

To provide a power consumption reduction device that can reduce power consumption of an electric device.SOLUTION: A power consumption reduction structure includes: wiring 7 which is associated with a building B and is connected to an outdoor power supply source 93; a plug connector 81 of the building B which is connected to the wiring 7; and a power consumption reduction device A. The power consumption reduction device A includes: a first member which is formed of Ni-Zn ferrite; and a second member which is laminated on a back surface of the first member, includes Fe as a main component, and is formed of a metal material including Cu, Nb, Ti, and Mn. The power consumption reduction device A is directly attached to the wiring 7 with the second member facing the wiring side.SELECTED DRAWING: Figure 4 【課題】電気機器の消費電力を低減できる消費電力低減装置を提供する。【解決手段】消費電力低減構造は、建築物Ｂに付随する配線７であって、屋外の電力供給元９３に接続されている配線７と、前記配線７に接続された建築物Ｂの差込接続器８１と、消費電力低減装置Ａと、を備える。消費電力低減装置Ａは、Ｎｉ−Ｚｎ系フェライトから形成された第１部材と、第１部材の裏面に積層され、Ｆｅを主成分として含み、且つ、Ｃｕ、Ｎｂ、Ｔｉ及びＭｎを含む金属材料から形成された第２部材と、を有する。消費電力低減装置Ａは、その第２部材を配線側に向けて配線７に直接的に取り付けられている。【選択図】図４
