The embodiment of the invention provides a mask as well as a manufacturing method and an evaporation method thereof. The mask comprises a mask body and a magnetic isolation layer, wherein the mask body is made of a metal material capable of being adsorbed by magnet; a first surface of the mask body comprises a pore formation area provided with multiple pores, and a first groove is formed between the edge of the mask body and the pore formation area in the first surface; the magnetic isolation layer is made of a material that cannot be adsorbed by the magnet; the magnetic isolation layer is arranged between the edge of the mask body and the pore formation area, and at least one part of the magnetic isolation layer fills the first groove. According to the mask disclosed by the invention, thegroove is formed in the edge of the mask body, and the groove is filled with the magnetic isolation layer. Compared with the prior art, the mask disclosed by the invention has the advantages that magnetic adsorption force on the edge can be reduced, the fold in the middle pore area can be smoothly spread to the edge, and fold accumulation can be avoided. Therefore, the aim of avoiding the fold ofthe mask is achieved.
