Zusammenfassung:	A manufacturing method of a back plate and a back plate for friction stir welding are provided. The manufacturing method of the back plate according to the present invention comprises: a groove processing step of processing a groove on a surface of a back plate; a first coating layer lamination step of laminating a first coating layer by coating a first coating material into the groove; and a second coating layer lamination step of laminating a second coating layer by coating a second coating material on the bottom surface of the groove. The back plate and a joining member can be easily separated even after friction stir welding of the joining member of a high melting point material. 백 플레이트의 제작 방법, 및 마찰 교반 용접용 백 플레이트를 제공한다. 본 발명에 따른 백 플레이트의 제작 방법은, 백 플레이트의 표면에 그루브를 가공하는 그루브 가공 단계, 제1 코팅재를 그루부 내에 코팅하여 제1 코팅층을 제1 코팅층 적층 단계, 및 그루부의 바닥면에 제2 코팅재를 코팅하여 제2 코팅층을 적층하는 제2 코팅층 적층 단계를 포함한다.
