To provide a powder coating device, a production method of an energy device, a positive electrode for a battery and a negative electrode for a battery capable of forming a powder layer with less layer thickness variation on the surface of a member.SOLUTION: A powder coating device has a transport device 9, a powder supply part 11 and a squeegee 2. The transport device 9 moves a sheet 4 in a prescribed direction. The powder supply part 11 supplies powders on a surface 4a of the sheet 4. The squeegee 2 is arranged so as to form a space between the sheet 4 and itself. The thickness of the powders 3 supplied on the surface 4a of the sheet 4 by the powder supply part 11 is adjusted. The squeegee vibrates at a frequency of 2 kHz or higher and 300 kHz or lower.SELECTED DRAWING: Figure 2 【課題】部材の表面上に膜厚のばらつきが少ない粉体層を形成することができる粉体塗工装置、エネルギーデバイスの製造方法、電池用正極、及び電池用負極を提供する。【解決手段】粉体塗工装置は、搬送装置９と、粉体供給部１１と、スキージ２と、を備える。搬送装置９は、シート４を所定の方向に移動させる。粉体供給部１１は、シート４の表面４ａ上に粉体を供給する。スキージ２は、シート４との間に隙間が形成されるように配置され、粉体供給部１１によってシート４の表面４ａ上に供給された粉体３の厚みを調整する。スキージは、周波数２ｋＨｚ以上３００ｋＨｚ以下で振動する。【選択図】図２
